The article discusses a new method to make images clearer and more detailed. The researchers used a technique called Binarization with Maximum Likelihood Estimation to enhance the contrast of images. This method helps to improve the quality of both two-tone and multi-tone images by adjusting the brightness and darkness levels. By separating the image into different parts and adjusting the histogram, the researchers were able to create sharper and more detailed images. The results showed that this new method is better at enhancing image contrast compared to other techniques.
