Embodiment Construction
[0057] The color image segmentation algorithm based on exponential moment pixel classification is characterized in that comprising:
[0058] Step 1: Decompose the three RGB components of the color image into exponential moments respectively, and select the calculated moments as the pixel-level features of the image, as follows:
[0059] Step 11: first decompose a color image into three channels of RGB;
[0060] Step 12: Construct each pixel for each channel in RGB local window of , select
[0061] in points 3×3 local window centered on ;
[0062] Step 13: Compute the exponential moments for each local window:
[0063] Step 131: Assume is the image in polar coordinates, define the exponential moments as follows
[0064]
[0065] in is a radial basis function, and the value range of k is all integers;
[0066]
[0067] Step 132: is an integral operation defined in the polar coordinates of the unit circle, and the digital image function is defined in Carte...
