Peak Signal to Noise Ratio is based on color texture based image segmentation by using the following equation.
It is the ratio between the maximum possible power of a signal and the power of corrupting noise that affects the fidelity of its image.To compare the proposed technique with existing technique, first PSNR parameter has use. We are measuring PSNR in decibel..

23 4.2 MSETo compare the proposed technique with existing technique, secondly MSE parameter has used.Mean Square Error is calculated pixel-by-pixel by adding up the squared difference of all the pixels and dividing by the total pixel count. MSE of the segmented image can be calculated by using the equation. ..
