Hello, these are my captcha images.
Characters are only from 0 to 8 (no 9)
Please provide at least 10 example images of the CAPTCHA system:
Please provide the full JavaScript source to what you've already tried:
var cbl = new CBL({
preprocess: function(img) {
img.debugImage("debugPreprocessed");
img.cropRelative(70, 2, 70, 2);
img.debugImage("debugPreprocessed");
img.binarize(20);
img.debugImage("debugPreprocessed");
},
character_set: "012345678",
exact_characters: 4,
pattern_width: 25,
pattern_height: 25,
pattern_maintain_ratio: true,
allow_console_log: true,
blob_console_debug: true,
perceptive_colorspace: false,
blob_debug: "debugSegmented"
});
I need advice, what else should I do so I can get rid of the lines in the background. I've read some solutions from issue 2019 till now. But what I did actually made it worse, such as using convolute and blur. so this is the only thing I think removes the line to be thinner.
Now there are still some characters sticking together and I'm a bit confused when playing the blob setting.
Thank you for your time.
