Updated 22 Nov Brightness Preserving Dynamic Fuzzy Histogram Equalization BPDFHE proposes a novel modification of the brightness preserving dynamic histogram equalization technique to improve its brightness preserving and contrast enhancement abilities while reducing its brivhtness complexity.

This technique, called uses fuzzy statistics of digital images for their representation and processing. Representation and processing of images in the fuzzy domain enables the technique to handle the inexactness of gray level values in a better way, resulting in improved performance.

Dynaamic, the imprecision in gray levels is handled well by fuzzy statistics, fuzzy histogram, when computed with appropriate fuzzy membership function, does not have random fluctuations or missing intensity levels and is essentially smooth. This helps in obtaining its meaningful partitioning required for brightness preserving equalization. Details of the method are available in.

Implementation of the technique for grayscale images is outright. The function brrightness on non-sparce images of type uint8, uint16, int16, double and single.

Undefined function or method ‘Brightness’ for input arguments of type ‘char’. This function can directly deal with any grayscale intensity image of form uint8, uint16, int16, single, double.

For color images you can just process the intensity plane as exemplified above. You need to do the spell check. The correction to the help file has been reflected and will be up soon. Call using ‘triangular’ and not ‘traingular’.

I believe your query is not related to this particular submission. I hope you do not mind dropping me a few lines on my email elaborating your requirement, and I would try to see on possibilities of helping you.

Hi, I need to compute the diagonal error weight matrix Wwhere W i,i measure the average local variance of pixels with gray level i. Can u please help me regarding this.

Can you provide me with attributes of the input image. Rows x Cols, DataType. Also, the custom parameters you are passing on. This is possibly an error internal to Matlab, yet I would try to look for some way out.

Maximum recursion limit of reached. Use set 0,’RecursionLimit’,N to change the limit. Data handling with images of classes uint16, int16 not restricted to gray values in [0,] and of type in single and double not restricted to [0,1] is restored in Rev 1.

File usage license within code modified for non conflict with BSD license clause. Example of implementation with color images added to the help documentation section. Data casting statements for output generation reduced with using cast. Output image mapped to gray-value range in input images of type single and double. Support error for images of type ‘uint16’, ‘int16’, ‘single’, and ‘double’ not explicitly mapped in the brightneess [0,1] or [0,] is resolved.
