Abstract |
JPEG 2000 is a widely used image coding standard for applications like Digital photography, video transmission and medical imagery. In the process of saving the images, since it processes one entire frame at a time, it consumes large power. During voltage scaling SRAM memory errors occurs in JPEG implementation. To reduce these memory errors, Contourlet transform technique is implemented in this project. This technique provides a flexible multi resolution, local and directional expansion for 2D images. These images are then transformed and sent through the Embedded Block Coding with Optimal Truncation (EBCOT) where compressed images are obtained. By Inversing this transform technique, decompressed image is obtained. Since this technique covers all the edges and smoothens the contours, we can reduce the loss of information/data thereby reduce the memory errors. This transform is advantageous since it does not require additional memory and circuit design is simple and more importantly reduces the power consumption and thus improves the image quality | |||||||||
