Remove specific color
Use openCV to remove
import pytesseract
import cv2
pytesseract.pytesseract.tesseract_cmd = 'C:\\Program Files (x86)\\Tesseract-OCR\\tesseract.exe'
img = cv2.imread('idText.png')
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
adaptiveThresh = cv2.adaptiveThreshold(gray, 255, cv2.ADAPTIVE_THRESH_MEAN_C, cv2.THRESH_BINARY, 35, 90)
config = '-l eng --oem 1 --psm 3'
text = pytesseract.image_to_string(adaptiveThresh, config=config)
print("Result: " + text)
cv2.imshow('original', img)
cv2.imshow('adaptiveThresh', adaptiveThresh)
cv2.waitKey(0)
Or apply morphological transformations (i.e. Erosion)
import cv2
image = cv2.imread('1.png')
gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
thresh = cv2.threshold(gray,105, 255, cv2.THRESH_BINARY_INV)[1]
thresh = 255 - thresh
kernel = cv2.getStructuringElement(cv2.MORPH_RECT, (3,3))
result = cv2.morphologyEx(thresh, cv2.MORPH_OPEN, kernel, iterations=1)
cv2.imshow('thresh', thresh)
cv2.imshow('result', result)
cv2.imwrite('result.png', result)
cv2.waitKey()
