INTRODUCTION The colored ultrasound images can better highlight the joint echotexture damage. OBJECTIVE To detect echotexture changes in joints of patients with rheumatic diseases, through a color histogram, and to correlate the area measurements with the gray scale (GS). METHODS Four patients with chondrocalcinosis, 5 patients with osteoarthritis and 1 patient with psoriatic arthritis were...

Motivated by the success of Deep Neural Networks in computer vision, we propose a deep Regularized Reconstruction Independent Component Analysis network (RICA) for RGB-D image classification. In each layer of this network, we include a RICA as the basic building block to determine the relationship between the gray-scale and depth images corresponding to the same object or scene. Implementing co...

This paper investigates Y UV -to-RGB color space conversion on FPGA-augmented TriMedia-32 processor. First, we outline the extension of TriMedia-32 architecture consisting of FPGA-based Reconfigurable Functional Units (RFU) and associated generic instructions. Then we analyse a YUV-RGB (RFU–specific) instruction which can process four pixels per call, and propose a scheme to implement the YUV-R...

The use of color in image processing is motivated by two principal factors; First color is a powerful descriptor that often simplifies object identification and extraction from a scene. Second, human can discern thousands of color shades and intensities, compared to about only two dozen shades of gray. In RGB model, each color appears in its primary spectral components of red, green and blue. T...

We calculate the orbital evolution of binary systems where the primary star is an evolved red giant branch (RGB) star, while the secondary star is a low mass main sequence (MS) star or a brown dwarf. The evolution starts when a tidal interaction causes the secondary to spiral-in. Either a common envelope (CE) is formed in a very short time, or the system reaches synchronization and the spiralin...

We analyze the angular momentum evolution from the red giant branch (RGB) to the horizontal branch (HB) and along the HB. Using rotation velocities for stars in the globular cluster M13, we find that the required angular momentum for the fast rotators is up to 1 − 3 orders of magnitude (depending on some assumptions) larger than that of the sun. Planets of masses up to five times Jupiter’s mass...

This paper describes the first results of an image recognition based location (IRBL) for a mobile application focusing on the procedure to generate a database of range images (RGB-D). In an indoor environment, to estimate the camera position and orientation, a prior spatial knowledge of the surroundings is needed. To achieve this objective, a complete 3D survey of two different environments (Ba...

Bilinear Heterogeneous Information Machine for RGB-D Action Recognition Report Title This paper proposes a novel approach to action recognition from RGB-D cameras, in which depth features and RGB visual features are jointly used. Rich heterogeneous RGB and depth data are effectively compressed and projected to a learned shared space, in order to reduce noise and capture useful information for r...

The superficial appearance and color of food are the first parameters of quality evaluated by consumers, and are thus critical factors for acceptance of the food item by the consumer. Although there are different color spaces, the most used of these in the measuring of color in food is the L*a*b* color space due to the uniform distribution of colors, and because it is very close to human percep...

We describe a three-step algorithm for the analysis of color images of flames, with the objective of analyzing the combustion process and its control parameters indirectly. The algorithm first extracts the interesting regions, applying a clustering method in the RGB color space, identifying and eliminating irrelevant regions and applying morphological operators. Then it calculates different geo...
