A comprehensive Contourlet transform toolkit for image feature extraction supporting customizable decomposition levels - for instance, three-level decomposition extracts 17-dimensional feature vectors suitable for texture analysis and SAR image segmentation applications.
In a MATLAB environment, a numerical simulation study was conducted using the db10 wavelet from the Daubechies wavelet family to compress speckle-degraded images. The research demonstrates that both threshold selection and decomposition levels significantly impact image compression quality. The implementation involves wavelet decomposition, thresholding operations, and reconstruction algorithms to analyze compression performance.
