Abstract Image sparse representation is a method of efficient compression and coding of
image signal in the process of digital image processing. Image after sparse representation,
to enhance the transmission efficiency of the image signal. Entropy of Primitive (EoP) is a
statistical representation of the sparse representation of the image, which indicates the
probability of each base element. Based on the EoP, this paper presents an image quality
evaluation method-Difference of Visual Information Metric (DVIM). The principle of this
method is to evaluate the image quality with the difference between the original image and
the distorted image. The comparative experiments between… More >
