I want to make a system like the Book Spine Recognition on Youtube.
So I read research paper and I built this system.
According this paper, I use Hough transform, then I recognize book boundary like this.
Then I want to separate each of these books. But what next step should I do? Please help me.
import cv2 import numpy as np img = cv2.imread('/Users/hogefuga/Desktop/20081104224105.jpg') gray = cv2.cvtColor(img,cv2.COLOR_BGR2GRAY) edges = cv2.Canny(gray,50,150,apertureSize = 3) lines = cv2.HoughLines(edges,1,np.pi/180,200) print(len(lines)) # 20本 for line in lines: for rho,theta in line: a = np.cos(theta) b = np.sin(theta) x0 = a*rho y0 = b*rho x1 = int(x0 + 1000*(-b)) y1 = int(y0 + 1000*(a)) x2 = int(x0 - 1000*(-b)) y2 = int(y0 - 1000*(a)) cv2.line(img,(x1,y1),(x2,y2),(0,0,255),2) cv2.imshow('output.jpg',img)
