Revision history [back]

Hi everyone!

I'm working on a project to convert handwritings into a plot from which I'll try to convert it into gcode. Here with Open CV I'm trying to find the best way to convert handwritings to Clear Plot.

Image original: I try to work in poor condition, hence the rotten quality of the paper:

After applying Candy edge i got this:

import cv2

import numpy as np

...

...

contours, hier = cv2.findContours(edgedImage.copy(), cv2.RETR_LIST, cv2.CHAIN_APPROX_SIMPLE)

mask = cv2.imread("./scripts/mask.png") # image white color

stencil = np.zeros(img.shape).astype(img.dtype)

color = [255, 255, 255]

# Fill out ALL Contours

for cnt in contours:

  cv2.fillPoly(stencil, cnt, color)

result = cv2.bitwise_and(img, stencil)

cv2.imwrite("result.jpg", result)

# Fill out ALL Contours

cv2.fillPoly(stencil, contours, color)

result = cv2.bitwise_and(img, stencil)

how am I supposed to get all the handwriting back, even the unclosed outlines?
