The objective of this work is to propose an image denoising technique and compare it with image denoising using ridgelets. The proposed method uses slantlet and
transform instead of wavelets in ridgelet transform. Experimental result shows that the proposed method is more effective than ridgelets in noise removal. The proposed method is effective in compressing images while preserving edges. Index Terms—ridgelet, slantlet transform, image denoising, compression, huffman, edge.
