applying ICA on multi lead ecg to extract foetal ecg

Canny edge detector algorithm matlab codes This part gives the algorithm of Canny edge detector. The outputs are six subfigures shown in the same figure: • Subfigure 1: The initial "lena" • Subfigure 2: Edge detection along X-axis direction • Subfigure 3: Edge detection along Y-axis direction • Subfigure 4: The Norm of the image gradient • Subfigure 5: The Norm of the gradient after thresholding • Subfigure 6: The edges detected by thinning

This is the parser of NMEA encoded data from GPS it separates lat and long

MATLAB雨燕程。电力系统电压骤降信号的小波分解结果(MATLAB Swift away. Power system voltage sag signal wavelet decomposition results)

this script is used for watermarking a text using converting text to 0, 1 symbols. this program uses Huffman coding and decoding for increasing capacity . finally returns 0 or 1 for validity check.
