How to make a binary image?
Steps we’ll use to preprocess our image: 1 Convert image to Grayscale – Images need to be converted into a binary image, so first, we convert the colored image to grayscale. 2 Thresholding is used to convert grayscale images into binary images. it decides whether the value of the pixel is below or above a certain threshold. All pixels below are turned to a white pixel, all pixels above are turned to a black pixel. 3 Now invert the image to using bitwise_not operation. 4 Applying various noise reduction techniques like eroding, dilating, etc. 5 Applying the text extraction method to the preprocessed image.
