Explore MATLAB source code curated for "图片" with clean implementations, documentation, and examples.
This program implements multi-level wavelet decomposition of images, extracting wavelet coefficients from each sub-band after decomposition using algorithms like Discrete Wavelet Transform (DWT) with functions such as wavedec2() for 2D signals.
MATLAB implementation for batch downsampling of multiple images to generate low-resolution versions using pixel reduction algorithms and interpolation techniques.
Identification of candidate ID numbers on answer sheets through grayscale conversion and image segmentation techniques, including practical applications for website development and enhancement.
"BP.m" contains the complete source code for the BP neural network model; "train.fig" shows the final training visualization; "population_data_original.fig" displays prediction result graphs; "matlab_command_window_output.txt" captures console messages during execution; "generated_data.mat" stores post-execution data files. .bmp files serve the same purpose as .fig files.
