1. Comparison of the discrete transform cosine and the discrete wavelet transform for image of compression of fingerprint / Comparação da transformada wavelet discreta e da transformada do cosseno, para compressão de imagens de impressão digital
This research aims to compare the following fingerprint image compression methods: the discrete cosseno transform (DCT), Haar wavelet transform, Daubechies wavelets transform and wavelet scalar quantization (WSQ). The main interest is to find out the technique with the smallest distortion and higher compression ratio. Image quality is measured using peak sig
