Hyperspectral image sensors are resource constrained and have limited on-board memory. Processing of high volume hyperspectral images pose a challenge to the memory and resources of the sensor. Contemporary wavelet based image compression schemes have intensive memory requirement of which 3D-WBTC have superior coding performance due to through the exploitation of the inter sub-band & intra sub-band redundancy. This paper presents a low memory implementation of 3D-WBTC which is a listless scheme by using the fixed size state memory to keep track of block set partitioning and significance testing of wavelet coefficients of transformed hyperspectral images. Memory access time is significantly reduced due to the elimination of lists that leads to reduced complexity. Simulation results of the proposed scheme shows that proposed coder is fast and have very low memory requirement thereby making it a suitable candidate for implementation in resource constrained hyper spectral image sensor.

Le présent article analyse les liens théoriques entre Henri Bergson et Gilles Deleuze dans le but d’examiner la mémoire et la répétition dans Un jour avec, un jour sans (Hong Sang-soo, 2015) et Syndromes and a Century (Apichatpong Weerasethakul, 2006). Ce travail examine en particulier la façon dont ces deux films articulent une structure double qui épouse une répétition systématique d’images, créant ainsi un sentiment prononcé de déjà-vu. L’analyse de ce phénomène s’appuie sur le schéma bergsonien du souvenir et de l’actualisation du passé. Cet article entend mettre en lumière l’expérience du temps dans les images cinématographiques selon Deleuze, en particulier en ce qui concerne les notions de cristal-image et de refrain. Ce type d’analyse vise également à souligner l’importance pérenne de la philosophie et du cinéma deleuziens dans le cinéma non européen, ainsi qu’à contribuer à l’établissement d’un lien entre le binôme cinéma-philosophie et le bouddhisme. Toutefois, l’objectif final de l’article est d’étudier la façon dont les deux films fournissent une compréhension fondamentale de la constitution du temps par le biais de la répétition. This article addresses key theoretical interconnections between Henri Bergson and Gilles Deleuze in order to explore memory and repetition in Right Now, Wrong Then (Hong Sang-soo, 2015) and Syndromes and a Century (Apichatpong Weerasethakul, 2006). In particular, it examines how both films articulate a dual structure which embraces a systematic repetition of images, thus developing a pronounced sense of déjà vu. This phenomenon is analyzed according to the Bergsonian schema of recollection-actualization of the past. This kind of analysis casts light on the experience of time in cinematographic images according to Deleuze, particularly regarding the notions of crystal-image and refrain. The article thus aims to highlight the enduring significance of Deleuzian film-philosophy in non-European cinema, also helping to establish an intimate connection between film-philosophy and Buddhism. However, its ultimate purpose is to address the way in which the two films give a fundamental understanding of the constitu­tion of time by means of repetition.

In the present study, a novel low memory coding algorithm for lossless image compression of hyperspectral images is proposed. The hyperspectral images are volumetric images that pose a challenge to the sensor memory. The contemporary transform-based compression algorithms exhibit remarkably efficient performance on the coding gain, complexity, and memory in comparison to other algorithms for lossy compression. The traditional 3D-DWT requires large memory for computation of wavelet coefficients of transform image. The fractional wavelet filter is a low memory solution to calculate the wavelet coefficients of the hyperspectral image. The 2D-ZM-SPECK is employed as a coding algorithm which is applied over HS image frame by frame basis. The simulation results indicate that the proposed compression algorithm has low memory requirements and high coding gain with less computational complexity. On observing the simulation results of the proposed compression algorithm, it is noticeable that the proposed coder is fast enough due to requiring low memory and hence proving its candidature in the implementation of a resource-constrained hyperspectral image sensor.

The association between intelligence and measures of the functions of the systems underlying attention and the recognition of verbal and image stimuli presented for memorization, as well as the lateral characteristics of speech memory were studied in members of an elderly age group (64.5 ± 6.3 years, n = 83; 43 women) and a young age group (22.0 ± 4.5 years, n = 133; 83 women). The rate of selection of information in conditions of conflict served as a predictor of the level of intelligence, independently of age. In elderly subjects, a higher level of intelligence corresponded to shorter executive control times, while no significant link between intelligence and functional measures of the attention system was seen in young people. Analysis of the properties of memory showed that reproduction of words addressed to the left hemisphere made a positive contribution to intelligence; in young people verbal memory for words addressed to the right hemisphere also made a contribution, while in elderly people there was a contribution from the efficiency of recognizing remembered verbal and image stimuli. Gender-linked features were seen in the age-related reorganization of the contribution of attention and memory to intelligence, with more marked changes in men.

Memory management of the hyperspectral image sensor is a challenging issue. The existing hyperspectral image compression schemes play a dominant role in minimizing the cost of storage equipment and bandwidth for data transmission for resource constraints onboard hyperspectral image sensors. Traditionally many transform-based set partition hyperspectral image compression algorithms are proposed, but these compression schemes use the data-dependent link list to keep track of the significant or insignificant coefficients or block cube sets, and the size of the lists increases swiftly with the encoding rate. The data-dependent list management and multiple memory read or write operations slow down the compression scheme. Many attempts had been made to address the memory issue through the replacement of the dynamic lists by the static fixed size state tables. The memory required for the state table depends upon the dimension of the hyperspectral image and at the low bit rates, it requires a lot of memory. This paper presents the novel hyperspectral image compression scheme for the hyperspectral image sensor that eliminates the linked list and state table. The obtained experimental results show that the proposed compression scheme outperforms state of the art transform hyperspectral image compression schemes in terms of coding memory and computation complexity while maintaining the coding efficiency. Due to the low complex nature, the proposed scheme saves the operation time and energy for the coding operation. The proposed compression scheme is a suitable candidate for the lossy data transmission and for the low memory hyperspectral sensors.

Listless set partitioning embedded block (LSK) and set partitioning embedded block (SPECK) are known for their low complexity and simple implementation. However, the drawback is that these block-based algorithms encode each insignificant subband by a zero. This generates many zeros at earlier passes because the number of significant coefficients at higher bitplanes is likely to be very few in a transformed image. An improved LSK (ILSK) algorithm that codes a single zero to several insignificant subbands is proposed. This reduces the length of the output bit string, encoding/decoding time and dynamic memory requirement at early passes. Furthermore, ILSK algorithm is coupled with discrete Tchebichef transform (DTT). This gives rise to a novel coder named as hierarchical listless DTT (HLDTT). The proposed HLDTT has desirable attributes like full embeddedness for progressive transmission, precise rate control for constant bit rate traffic and low complexity for low power applications. The performance of HLDTT is assessed using peak-signal-to-noise-ratio (PSNR) and structural-similarity-index-metric (SSIM). Extensive simulation conducted on various standard test images shows that HLDTT exhibits significant improvement in PSNR values from lower to medium bit rates. At the same time, HLDTT shows improvement in SSIM values on all bit rates.

No particular dagger was the object of Macbeth's hallucination of a dagger. In contrast, when he hallucinated his former comrade Banquo, Banquo himself was the object of the hallucination. Although philosophers have had much to say about the nature and philosophical import of hallucinations (e.g. Macpherson and Platchias, Hallucination, 2013) and object-involving attitudes (e.g. Jeshion, New essays on singular thought, 2010), their intersection has largely been neglected. Yet, object-involving hallucinations raise interesting questions about memory, perception, and the ways in which we have knowledge of the world around us. In this paper, I offer an account of object-involving hallucinations. Specifically, I argue that they are an unusual species of perceptual remembering.

When the mind turns more than one would wish towards questions of - as W.G. Sebald puts it - the \"natural history of destruction\", comparative consideration by artists and interdisciplinary scholars is directed to the interstices between images, novel, essay, (auto)biography, memorial and travelogue. Artists have been among Sebald's most prolific interpreters - as they are among the more fearless and holistic researchers on questions concerning what it means never to be able to fix an identity, to tell a migrant's story, or to know where a historical trauma ends. Sebald has - as this book attests - also given artists and scholars a means to write with images, to embrace ambiguity, and to turn to today's migrants with empathy and responsibility; as well as to let academic research, creation and institutional engagement blend into or substantially inform one another in order to account for and enable such necessary work in the most diverse contexts.

This article explores the psycho-social space between autobiographical and collective memory concerning massive social traumas. It is conceptualized that there is a third type of memory image, termed “my-their.” Individuals appear to “remember” autobiographical memories of elder family members, even though they could not, either because they were born after the trauma happened or because the autobiographers were extremely young at the time of the experience. These emotional “memories” furthermore connect to collective memories of social traumas of ethnic/national groups. Examples from memories of the Holocaust and al Naqba are examined. Furthermore, the roles that “my-their” memory images can play in peace building and reconciliation are discussed.

The chronicles of the conquest, the stories of the explorers of the colony and the early republic, and forced displacement due to contemporary violence, have revealed an important relationship between violence and territory whose plastic incarnation is witnessed in a series of images that also represent the memory of the opprobrious facts pertaining to the Colombians’ past history. In this article, we outline the possibility of accessing a sort of topographical or spatial dimension of memory through various images in which this relationship between territory and violence is patently revealed. In order to fulfill the purpose of the article, we will try to demonstrate how the way in which a compositional form such as the montage, characterized by the historiographic practice of Aby Warburg, can render account of the poetics of space that is expressed in some travelers’ images of the nineteenth and twentieth centuries.
