The revision of conversion formula from RGBcolor spaceto HSVcolor space; 从RGB到HSV色彩空间转换公式的修正 2. A new image pre-processing method based on linear transformation of YUVcolor space; 基于YUV色彩空间线性变换的图像预处理方法 4) HSV color space ...
Firstly,self-adaptive thresholding algorithm is used after that a RGB image is converted to the YCbCr color space. 首先把RGB图像转换到YCbCr色彩空间后对Cb通道图像进行自适应阈值分割;然后对图像采用投影法获取准确的手部图像;利用提取的手部图像Hu矩特征值作为样本数据训练SVM模型,最后利用训练好的分类器对手...
Color spaceBecause of the powerful data processing ability of FPGA, the fast interpolation algorithm is used for Bayer format data which comes from CMOS sensor MT9M011 to convert to RGB image format. In the RGB color space to YCbCr space conversion stage, using color space conversion formula,...
The formula is : Y = (y - 128) * C /128 + (B - 128) + 128. //About add 128 is ture or error ? Cb = [ (Cb - 128)*cos(H) + (Cr - 128)*sin(H)] * S/64 + 128. Cr = [-(Cb - 128)*sin(H) + (Cr - 128)*cos(H)]* S/64 + 128. ...
