Interface for Microsoft Audio compresSion Manager. - Delphi Source
The ACM uses existing driver interface hooks to override the default mapping algorithm for waveform audio devices. This allows the ACM to intercept device-open calls. After a call has been intercepted, the ACM can perform a variety of tasks to process the audio data, such as inserting an external compressor or decompressor into the sequence.
Image compresSion
A collection of simple routines for image compresSion using different techniques.
圖象壓縮的不同方法
BTCODE:
Image compresSion Using Block Truncation Coding.
PYRAMID:
Image compresSion based on Gaussian Pyramids.
DCTCOMPR:
Image compresSion based on Discrete Cosine Transform.
IMCOMPR:
Image compresSion based on Singular Value Decomposition.
The given codes can be also used in 2D noise suppression.
Notes:
The function "conv2fft" performs a 2D FFT-based convolution.
Type "help conv2fft" on Matlab command window for more informations.
