Hi everybody! I've started to segment an image for an academic work, but I'm struggling in remove texts in the image. While segmenting those images these texts are also segmented along with the region of interest. I want to remove those text from images before to continue with others process.

The image was uploaded via an Hyper link in the description of the problem sir. But you can click here to have the access to the image file. I didn't upload the file directly with the problem's description because the chat box didn't support .tif files.
Thanks!

I'd to a closing or dilation with imclose() or imdilate() This will connect the letters and numbers together into a bigger blob. Then I'd to an opening or erosion to break the connections with the thin lines that run all over the place. Then I'd use bwareafilt() to extract out blobs of the size that the number/letter groups are. Then use that as a mask to erase them from the image. Here's a start
se = strel('disk', 4, 0);
mask = imclose(originalImage, se);
mask = imopen(mask, se);
originalImage(mask) = 0;
Adapt as needed.
