Learnable Image Encryption [article]

Masayuki Tanaka
2018 arXiv   pre-print
The network-based machine learning algorithm is very powerful tools. However, it requires huge training dataset. Researchers often meet privacy issues when they collect image dataset especially for surveillance applications. A learnable image encryption scheme is introduced. The key idea of this scheme is to encrypt images, so that human cannot understand images but the network can be train with encrypted images. This scheme allows us to train the network without the privacy issues. In this

Network Analysis for Explanation [article]

Hiroshi Kuwajima, Masayuki Tanaka
2017 arXiv   pre-print
Safety critical systems strongly require the quality aspects of artificial intelligence including explainability. In this paper, we analyzed a trained network to extract features which mainly contribute the inference. Based on the analysis, we developed a simple solution to generate explanations of the inference processes.

Dario Maestripieri (ed): Primate psychology

Masayuki Tanaka
2004 Primates  
This book is a very good handbook for young behavioral scientists or psychologists. Consisting of an introduction and 15 chapters contributed by 29 researchers, it is very helpful to scientists who work with nonhuman animals as well as those who study human behavior or psychology. Every chapter reviews work on both human and nonhuman primates and tries to integrate the two areas, so that researchers in either field will learn about new work in the other area. Primate psychology is also a great

The list of both historical works from the nineteenth century and very recent works will be helpful not only to young scientists but also to anybody having an interest in behavioral sciences in human and nonhuman primates. The book begins by providing a definition of psychology and by explaining the significance of behavioral study in nonhuman animals. According to the editor, the human mind, as well as human language and culture, is unique to the species. Therefore, the creation of an integrative discipline that studies the mind and behavior of all primates is an important first step toward understanding the mind. Next, a brief history of primate psychology is given, starting with Charles Darwin. Researchers will find that current topics in the book are based on the foundations laid by pioneers such as Wolfgang Ko¨hler, Robert Yerkes, Harry Harlow, and Robert Hinde. The editor writes that the goal of this book is to integrate the behavioral research on humans with that on nonhuman primates and to encourage communication between students of primate and human behavior. The emphasis of this book is on social processes that vary greatly between species and that are expected to have evolved especially in human and nonhuman pri-mates. Therefore, aspects of behavior and cognition that are not strictly social (e.g. foraging, spatial cognition) are not presented. The editor hopes that this book will encourage researchers studying all primate species to relate their work to human behavior. A brief summary of the chapters follows. In Chap. 2, J. Dee Highly gives a discussion of aggressive behavior and its neurobiological substrates in primates and humans. In Chap. 3, Peter Judge tries to synthesize and integrate research on conflict resolution, focusing on both similarities and differences across species and contexts. This chapter emphasizes the perspective of social processes and suggests a "process model" to depict the factors involved in dyadic conflict resolution and the circular nature of conflicts. In Chap. 4, Kim Wallen and her colleagues focus on primate sexuality and address sex differences in behavioral development, as well as the social and neuroendocrine aspects of sexual behavior and sexual motivation in adolescence and adulthood. In Chap. 5, Dario Maestripieri, the editor of the book, discusses the conceptual premises of attachment theory and the parallels between attachment processes in primates and humans. He encourages a complementary effort on the part of those studying human attachment to incorporate the comparative and biological perspectives provided by primate research into their work. In Chap. 6, Lynn Fairbanks takes an evolutionary approach to the study of parenting and emphasizes the adaptive value of individual differences in parenting styles. This chapter presents evidence of trade-offs in mother-offspring interactions as they change over time, in the role of fathers in infant care, and in the effects of social and demographic factors influencing maternal care such as the mother's age, the presence of grandmothers, and the family's status. In Chap. 7, James Roney and Dario Maestripieri contrast biological and social perspectives on behavioral development, including the effects of parenting styles on development and the determinants of behavioral sex differences. The authors also compare different approaches to studying altruistic interactions and the

Correspondence and Opinions are some melanin granules in the horny layer around the eccrine ducts (fig. 2c and d in Palleschi et al.), which seem to derive from intra-epidermal naevus cells (fig. 2g and h in Palleschi et al.). A high density of melanin granules is observed in the papillary dermis in their figure 2e shown by somewhat globular masses, which seem to correspond to the dermoscopic image of their figure 2b. The reason for the blurred blue-grey globules on dermoscopy is thus

First, histology of the upper portion of the horny layer was not shown. The presence of melanin granules in the horny layer should not be ignored when considering the dermoscopic image of AMN. We imagine that the melanin granules are less prominent in the horny layer in this case because of fewer nests of naevus cells in the epidermis. Second, only haematoxylin-eosin staining was used in this study. As we described, with haematoxylin-eosin staining, the epidermis and horny layer are so darkly stained that the melanin granules cannot be distinguished clearly from the surrounding tissue. In order to evaluate melanin granules in the epidermis or horny layer precisely, our modified Fontana-Masson stain would be a solution. Third, this study was based on two-dimensional images, and there are only a few horizontal sections shown; therefore, it cannot be fully clarified which levels of melanin granules mostly contribute to the dermoscopic image in the horny layer, the basal layer and the papillary dermis. In addition, the spatial positional relation between the histological structure and the dermoscopic one is difficult to determine from a two-dimensional image. Therefore, we think that more three-dimensional studies are needed for a thorough understanding of dermoscopic images.

Gradient-Based Low-Light Image Enhancement [article]

Masayuki Tanaka, Takashi Shibata, Masatoshi Okutomi
2018 arXiv   pre-print
A low-light image enhancement is a highly demanded image processing technique, especially for consumer digital cameras and cameras on mobile phones. In this paper, a gradient-based low-light image enhancement algorithm is proposed. The key is to enhance the gradients of dark region, because the gradients are more sensitive for human visual system than absolute values. In addition, we involve the intensity-range constraints for the image integration. By using the intensity-range constraints, we

Experiments demonstrate that the proposed gradient-based low-light image enhancement can effectively enhance the low-light images.
