Abstract
Image compression is a method through which we can reduce the storage space of images, videos
which will helpful to increase storage and transmission process’s performance.
In image compression,
we do not only concentrate on reducing size but also concentrate on doing it without losing quality and
information of image.
In this paper, two image compression techniques are simulated.
The first
technique is based on Discrete Cosine Transform (DCT) and the second one is based on Discrete
Wavelet Transform (DWT).
The results of simulation are shown and
