Mean squared error in image processing
WebApr 18, 2024 · Image segmentation is the technique and process of dividing an image into regions with specific characteristics and extracting the target of interest, which is a key step from image processing to image analysis. Image segmentation is applied in many aspects. WebNov 19, 2010 · The LMSE package contains two subroutines. LMSE computes the minimum mean square error (MSE) possible if one image is allowed to be linearly scaled in intensity. LMSEDIFF computes the difference image after the target image is scaled according to the scaling that minimizes the MSE.
