A variety of devices for image capture, printing, and display respond according to a power law. The exponent in power law equation is referred to as gamma Þ ...

A power law is a functional relationship between two quantities, where a relative change in one quantity results in a relative change in the other quantity

由下圖可見Power-Law相較於log的轉換幅度較小，因此若資料不須不如log如此敏感之轉換曲線時可採用Power-Law。其轉換公式如下。

This work aims to improve the efficiency of enhancing complex images through adaptive power-law intensity transformations in automatic mode. In this paper, a ...

In this paper, we present a new approach for the enhancement of a highly underexposed color image using a power-law transformation operator.

Power law curves with γ <1 map a narrow range of dark input values into a wider range of output values, with the opposite being true for higher input values.

For example, old CRT monitors have an intensity-to-voltage response which is a power-law with exponents varying from 1.8 to 2.5.

In this paper, we present a new adaptive spatial domain contrast and sharpness enhancement method, in which modified powerlaw transformations function is ...

In this lecture we will learn how to perform power-law transformation of image using Matbal. In last two lectures we learned how to do ...
