There are many libraries which are used to Image processing applications. But the algorithms behind these libraries use basic mathematical operation. I hope to bring you series of blog posts which describe the fundamental image processing algorithms implemented in mathematical operation without using any library. Following java class change the brightness of an image.
We should input our image to the method changeBrightness as a BufferedImage. increasingFactor is an integer which determine the brightness level of the image. Positive values will increase the brightness while negative values decrees. Range of the increasingFactor should be between -255 to 255.
