The proposed method is called hybrid classified vector quantization. It involves a simple but efficient classifier-based gradient method in the spatial domain, which employs only one threshold to determine the class of the input image block, and uses three AC coefficients of discrete cosine transform coefficients to determine the orientation of the block without employing any threshold. The proposed technique is benchmarked with each of the standard vector quantizers generated using the k-means algorithm, standard classified vector quantizer schemes, and JPEG-2000. Simulation results indicate that the proposed approach alleviates edge degradation and can reconstruct good visual quality images with higher peak signal-to-noise ratio than the benchmarked techniques, or be competitive with them.<\/jats:p>","DOI":"10.1117\/1.3116564","type":"journal-article","created":{"date-parts":[[2009,4,21]],"date-time":"2009-04-21T18:02:07Z","timestamp":1240336927000},"page":"1-13","source":"Crossref","is-referenced-by-count":4,"title":["Novel hybrid classified vector quantization using discrete cosine transform for image compression"],"prefix":"10.1117","volume":"18","author":[{"given":"Ali H.","family":"Al-Fayadh","sequence":"first","affiliation":[{"name":"Liverpool John Moores Univ."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abir Jaafar","family":"Hussain","sequence":"additional","affiliation":[{"name":"Liverpool John Moores Univ."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paulo","family":"Lisboa","sequence":"additional","affiliation":[{"name":"Liverpool John Moores Univ."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dhiya","family":"Al-Jumeily","sequence":"additional","affiliation":[{"name":"Liverpool John Moores Univ."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"189","reference":[{"key":"10.1117\/1.3116564_r1","doi-asserted-by":"crossref","unstructured":"A.
