The logarithmic transformation changes the brightness distribution of an image by taking the logarithm of the gray value of each pixel, which is a common method for image gray level transformation. The logarithmic transformation can improve imaging quality under uneven lighting conditions and also adjust high dynamic range data. The following provides example code for … Read more

Color images (RGB), also known as true color images, are typically represented by three color components: red (R), green (G), and blue (B), with values ranging from [0,255]. Taking the reading, assignment, and display of a 24-bit true color image as an example, including matrix representation, matrix assignment, value retrieval, and single (color) channel display. … Read more
Introduction FPGAs are widely used in various image processing applications, including medical and scientific imaging, space imaging, automotive, and defense fields. No matter which solution is used, the advanced algorithms may differ, but the fundamental parts are the same: they all need to connect to an image sensor or camera, process the captured images, and … Read more
Butteraugli: An Open Source C++ Library for Measuring Perceptual Differences in Images Butteraugli is an open-source project developed by Google for measuring the perceptual differences between two images. Its name sounds interesting, but its functionality is very powerful. It not only provides a scalar score to represent the differences between two images but also generates … Read more
Differences Between RGB to YCrCb Conversion in OpenCV and MATLAB Introduction Recently, while rewriting an image processing project from MATLAB to Python, I discovered that the results from the two were different. Upon investigation, I found that the default functions for RGB to YCrCb conversion in OpenCV and MATLAB yield different results. In this article, … Read more
