A NOVEL METHOD ON FINGERPRINT IMAGE COMPRESSION

Abhilasha A.P, Laya Tojo

Abstract: Here a new technique of fingerprint compression is introduced. Fingerprint compression is a challenging task in storage and communication media because more amount of image has to stored, processed and transformed in many applications. Here the dictionary is obtained from the preprocessed fingerprint patches which are represented as linear combination of sparse method. After the dictionary is formed L-norm minimization is done to find similar blocks and Huffman encoding for effective compression. This proposed method can increase the performance in terms of quality as well as compression. The output is compared with the existing techniques such as JPEG compression method and K-SVD compression method. Finally result analysis is made based on performance parameters such as PSNR and MSE.

Keywords: Compression, Huffman Encoding, DCT, PSNR, MSE.
