Image analysis and understanding are challenging tasks, usually having segmentation as a major step. Boundary detection is a type of segmentation which aims to highlight the boundaries of the objects in a scene. Models based on Convolutional Neural Networks (CNN) have presented promising results for...

In particular the Illuminant and the Linearity of the RGB color space. Convert your RGB color to CIE L*a*b* and then we can get the L* out, which is the perceived lightness.More often than not an RGB image will be encoded in non-linear sRGB color space with 8 bits per channel, ...
If you must save in a color model other than RGB or Lab, keep a copy of the original graphic. RGB and Lab color models represent larger color gamuts than most output devices can reproduce, retaining as much color information as possible before being translated to a smaller output color ...
They are based on replacing the power-function nonlinearities in CIELAB and IPT with more physiologically plausible hyperbolic functions optimized to most closely simulate the original color spaces in the diffuse reflecting color domain. This paper presents the formulation of the new models, evaluations...

The combination of two approaches of image texture (histogram statistics and gray-level co-occurrence matrix) and two color models (RGB, YIQ), should be considered in the application of digital image processing of equine IRT. Keywords: effort; infrared thermography; image texture; noninvasive; ...
Learn about color models and color spaces such as RGB, CMYK, HSB, Lab, and Grayscale to choose the correct colors for your artwork. Also, learn about spot and process colors.
For the top two state-of-the-art methods, CSRNet and NeurOp, we retrained their models under the same experimental conditions as ours to ensure a fair comparison. Quantitative comparison The results presented in Table 1 demonstrate that our proposed model outperforms the previous state-of-the-...
Hawkins' statistical test on the normality and homoscedasticity (common covariance matrix) of the estimated Gaussian mixture models is performed and McLachlan's bootstrap method is used to test the number of components in a mixture. Experimental results show that the estimated Gaussian mixture model ...
