If characters touch each other (even minimally), vertical projection will fail. In this challenge, characters are guaranteed not to touch. However, if your preprocessing adds artifacts that connect characters, segmentation may break. Always check intermediate steps by saving the processed images to disk.

By converting the image to grayscale and applying a strict black-and-white threshold filter, background noise and colored interference lines drop out of the array. This leaves clean, high-contrast character silhouettes that are easy for algorithms to read. Phase 3: OCR Processing and Submission captcha me if you can root me

Are there in the image (like lines or dots) that are confusing the OCR? Which operating system are you running your script on? Share public link If characters touch each other (even minimally), vertical

A second challenge appeared: not a picture, but a riddle. Always check intermediate steps by saving the processed

If text CAPTCHAs are used, overlapping characters, complex background noise wave patterns, and variable fonts prevent basic thresholding algorithms from isolating characters.
