Classic wavelet texture segmentation is a fundamental image processing technique that segments different texture regions in images through wavelet transformation and threshold processing. In MATLAB implementation, this method can be efficiently executed using built-in functions like wavedec2 for 2D discrete wavelet decomposition and wthresh for thresholding operations. The process typically involves decomposing the image into multiple frequency subbands, applying appropriate threshold values to wavelet coefficients, and reconstructing the segmented image using waverec2. This technique finds extensive applications in image processing, pattern recognition, and computer vision domains, enabling researchers to better analyze and understand texture information within images. Key implementation parameters include wavelet type selection (e.g., Haar, Daubechies), decomposition level, and threshold determination methods (global or adaptive).
