WebTorchJPEG. This package contains a C++ extension for pytorch that interfaces with libjpeg to allow for manipulation of low-level JPEG data. By using libjpeg, quantization results are guaranteed to be consistent with other applications, like image viewers or MATLAB, which use libjpeg to compress and decompress images.

Then just take the FFT and multiply that vector by a phase ramp. Finally take only the real part and you have the DCT. Here's the code in MATLAB. rite aid bailey delavan buffalo
