I want to Quantization HSV Space by assigning 8 level each to hue, saturation and value to give a quantized HSV space with 8x8x8=512 histogram bins. I have used the following code for that but I am getting an error in rescale function. Can anyone help me to sort out this problem?
histogram of the image (or video) in a non-equal manner on the basis of the number a color appearance frequencies.;SOLUTION: The section of the bin value of the color histogram is quantized on the basis of the number of color appearance frequencies in a non-equal manner.;COPYRIGHT: (C)...
The proposed algorithm provides a much simpler hardware (H/W) structure than the bi-histogram equalization since it is based on the cumulative density function of a quantized image. Thus, the realization of bi-histogram equalization in H/W is feasible, which leads to versatile applications in ...
An image enhancement circuit and a method therefor including the steps of quantizing the level of an input image signal, obtaining a cumulative density function on the basis of a gray level distribution of a screen unit with respect to the quantized image signal, outputting a cumulative density ...
Reversible fragile watermarking for locating tampered blocks in JPEG images This paper proposes a novel fragile watermarking scheme for JPEG image authentication. The watermark is generated by folding the hash results of quantized ... Xinpeng,Zhang,and,... - 《Signal Processing》 被引量: 121发表:...
6.43. In the embedding process, high-frequency subbands of the cover image are divided into blocks. For each block, a new histogram shifting method is applied to the local histogram generated from all quantized wavelet coefficients in the block. The detailed embedding process is described as ...
Also, in order to reduce the hardware of the circuit, an input luminance image is quantized, the quantized image is divided into a predetermined number of quantized subimages on the basis of the mean of the quantized image, and an independent histogram equalization is performed on each of the...
