The book is divided into ten chapters. We start with some examples and a description of multimedia databases. In addressing multimedia information, we are addressing digital data representations and how these data can be stored and manipulated. Multimedia data provide additional functionality than would be available in traditional forms of data. It allows new data access methods such as query by images in which the most similar image to the presented image is determined.

Deep generative models such as variational autoencoders (VAEs) and generative adversarial networks (GANs) generate and manipulate high-dimensional images. We systematically assess the complementary strengths and weaknesses of these models on single-cell gene expression data.

Hand gesture recognition has been researched for a long time. However, performance of such methods in practical application still has to face with many challenges due to the variation of hand pose, hand shape, viewpoints, complex background, light illumination or subject style. In this work, we deeply investigate hand representations on various extractors from independent data (such as RGB image and Depth image).

Further advances in modern microscopy are leading to teravoxel-sized tiled 3D images at high resolution, thus increasing the dimension of the stitching problem of at least two orders of magnitude. The existing software solutions do not seem adequate to address the additional requirements arising from these datasets, such as the minimization of memory usage and the need to process just a small portion of data.

This paper contributes an efficient denoising method for low-dose CT images. A noisy image is decomposed into three component images of low, medium and high frequency bands; noise is mainly presented in the medium and high component images. Then, by exploiting the fact that a small image patch of the noisy image can be approximated by a linear combination of several elements in a given dictionary of noise-free image patches generated from noise-free images taken at nearly the same position with the noisy image, noise in these medium and high component images are effectively eliminated.

Rapid improvements in light and electron microscopy imaging techniques and the development of 3D anatomical atlases necessitate new approaches for the visualization and analysis of image data. Pixel-based representations of raw light microscopy data suffer from limitations in the number of channels that can be visualized simultaneously.

Land cover classification is one of the main components of the modern weather research and forecasting models, which can influence the meteorological variable, and in turn the concentration of air pollutants . In this study the impact of using two traditional land use classifications, the United States Geological Survey (USGS) and the Moderate-resolution Imaging Spectroradiometer (MODIS), were evaluated. The Weather Research and Forecasting model (WRF, version 3.2.1) was run for the period 18 - 22 August, 2014 (dry season) at a grid spacing of 3 km centered on the city of Manaus.

This study investigates men and women’s representations in TV advertisements in Vietnam from a multimodal critical discourse analysis perspective. The data comprise of almost one hundred TV advertisements aired on principle TV channels in Vietnam such as VTV and HTV. The framework in use is Fairclough’s (2001), in which part of Kress and van Leeuwen’s visual grammar (1996) is incorporated for a multimodal discourse analysis of the advertisements.

Recently, Russell (2003) performed a similar study, also by using artworks to test Bartlett
s concept of effort after meaning (Bartlett, 1932). In accordance with Bartlett
s pre- diction, in a within-subjects design, Russell (2003) found an increase in the meaningfulness and hedonic value from first to second ratings when the paintings were presented with descriptions in the second phase (description plus title and the artist
s name). In Russell
s study, images of abstract and semiabstract art were presented. A comparison between abstract and representational art was not made.

Beginning with modest initial attempts in roughly the 1960s, digital image processing has become a recognized field of science, as well as a broadly accepted methodology, to solve practical problems in many different kinds of human activities. The applications encompass an enormous range, starting perhaps with astronomy, geology, and physics, via medical, biological, and ecological imaging and technological exploitation, up to the initially unexpected use in humane sciences, e.g., archaeology or art history.

Brain Imaging Applications With the advent of new anatomical and functional brain imaging methods, it is now possible to collect vast amounts of data from the living human brain. It has thus become very important to extract the essential features from the data to allow an easier representation or interpretation of their properties. This is a very promising area of application for independent component analysis (ICA). Not only is this an area of rapid growth and great importance; some kinds of brain imaging data also seem to be quite well described by the ICA model.

A fundamental approach in signal processing is to design a statistical generative model of the observed signals. The components in the generative model then give a representation of the data. Such a representation can then be used in such tasks as compression, denoising, and pattern recognition. This approach is also useful from a neuroscientific viewpoint, for modeling the properties of neurons in primary sensory areas. In this chapter, we consider a certain class of widely used signals, which we call natural images....
