The purpose of this project was to build an algorithm that can understand a small library of 10 simple commands while being able to ignore, or distinguish from, unknown commands. I submitted this work for the Udacity Machine Learning Engineer Nanodegree in June 2018.

JPEG compression implemented using the discrete-cosine transform

[Under Construction]A collection of experimental results of various image / video / point cloud processing algorithms

Digital Image Reconstruction

Repository for all the codes created during Digital Image Processing course at SEAS, Ahmedabad University during Winter 2018 (Semester 6).

Image compression using the discrete cosine transform

Fast Discrete Cosine Transform (FCT) using an FFT optimzed for real input sequences

A tool for instrument recognition.

Algorithm compresses image by taking diagonal averages of pixels and storing every four pixels in one pixel which reduces size significantly. Most images tested don't lose more than 2%. Decompression algorithm implemented too. Have fun trying it with the display in a ssh -X. Make sure you install X-quartz :)
