in [16], and defined with color features I1, I2' and I3', as the Ohta color space.) We used OpenCV (Open Source Computer Vision, http://opencv.org/) functions to convert input images into the following color spaces: YCbCr (implemented in OpenCV as YCrCb), HSV, HLS, CIE L*a*b* and CIE L*u*v*.
To obtain better color evaluations, we transform the RGB image to the YCrCb representation.
Regarding object segmentation, a color image segmentation algorithm based on the YCrCb threshold is adopted.
Colour transforms RGB to YCrCb Depending on the conversion require application, W x H x 9 images can be multiplications captured in and W x H x 6 binary, grey additions/ scale, or colour subtractions.
When color videos need to be processed, the circuit, as reported in [19], can be fed with the luminance channel of the YCrCb color space.
