Parameter estimation of image gamma transformation based on zero-value histogram bin locations

作者：

Highlights：

•

• New Zero-Value Histogram Bins (ZVHBs) emerge in gamma transformed image histogram.

• The number of ZVHBs is exploited to estimate the parameter approximately.

• The locations of ZVHBs are matched to further estimate the parameter accurately.

• The method is applied for image restoration.
