Hi Happy,
Are the white words (pixel value 255) the only true white in the image?
For example, when we take images, we usually ensure that there is no white in the images, i.e. any other areas that appear to be white are actually lower values.
Also, are they colour images or greyscale? The reason for my question is that I do have a simple macro that we use to take out white borders and it might work for your text but ONLY if the text pixels are the only 255 value pixels in the image.
Kind regards,
Jacqui

Hi i want to remove unwanted images such as words(white 255) from my image, but i do not want my main image to be affected. For example, loss of white patches of my main images.
lets say there is a tumour in the middle, i want to get rid of the patient ID.
Please help. Thank You.
