The (VI (S) TA) Image Coding Toolbox ( VistaCoderTools ) is a Matlab Toolbox for achromatic and color image coding that includes a set of DCT algorithms based on Human Vision Models of different accuracy and SVM selection of transform coefficients. This toolbox summarizes a decade of work improving the JPEG standard by improving the underlying human vision model and taking into account natural image statistics [Malo95 , Malo99 , Malo00 , Epifanio03 , Gomez05 , Malo06 , Gutiérrez07 , Camps08 , Simon08 ]. Citation: We have decided to make the library available to the research community free of charge. If you use VistaCoderTools in your research, we kindly ask that you reference this website: J. Malo, J. Gutiérrez, G. Camps, I. Epifanio, G. Gómez and M. Simón. "VistaCoderTools: a DCT image coding toolbox for Matlab" , http://www.uv.es/vista/vistavalencia/software/software.html
and the paper(s) associated to each algorithm.
Installation:
Basic features (achromatic images):
Applies one of the above models to generate file(s) at the desired target entropy(ies), measured in bits / pixel (i.e. file size / number of pixels)
Decodes the files generated by vista_encoder_achrom.m
Shows an example of the encoding-decoding process Basic features (Color Images*): * Patent pending, Color features are included in VistaCoderTools2.0 (not available on-line)
Applies one of the above color models to generate file(s) at the desired target entropy(ies), measured in bits / pixel (i.e. file size / number of pixels)
Decodes the files generated by vista_encoder_color.m
Shows an example of the encoding-decoding process
Some Results:
Color images at 0.95 bits/pix
