Binarization of image in matlab
WebMay 4, 2016 · The most important thing is to become familiar with this binarization algorithm because it is a simpler algorithm among digital image processing techniques and does not contain any abstruse mathematic formulas. It requires only setting up thresholds and then comparing sizes to determine black or white. WebOpen main.m in your MATLAB editor and find DATASET in line 35. As you'd expect, we should set it to 'AirChangeDataset'. Then, find the CONFIG_DATASET term in line 40. Change the first string within the braces to the absolute path of the unzipped dataset.

WebJun 14, 2016 · The answer is that imbinarize takes an image as input, although Otsu's method does not require the original image, only the image's histogram. If you have a situation where you want to compute a threshold based only on a histogram, then you can call otsuthresh directly. That's why it is there.
