My Project 1:

 Freedom Fighter Recognition System using OpenCV:

This project uses the concept of template matching (in OpenCV) and object detection. 

The project takes a source image and a template/patch. Here the source image is a collage of freedom fighters and a template (eg Bhagat Singh). It compares both source and the template by finding the matching probability and encircles the portion in the source image with maximum matching probability.

Source Image:

Template:

Final Output:

Code:

import cv2

import numpy as np

FreedomFighters=cv2.imread("freedomfighters.jpg",cv2.IMREAD_UNCHANGED)

cv2.imshow("Image",FreedomFighters)

cv2.waitKey()

cv2.destroyAllWindows()

BhagatSingh=cv2.imread("bhagatSinghpic.jpg",cv2.IMREAD_UNCHANGED)

cv2.imshow("Image",BhagatSingh)

cv2.waitKey()

cv2.destroyAllWindows()

result=cv2.matchTemplate(FreedomFighters,BhagatSingh,cv2.TM_CCOEFF_NORMED)

min_val,max_val,min_loc,max_loc=cv2.minMaxLoc(result)

h=BhagatSingh.shape[0]

w=BhagatSingh.shape[1]

cv2.rectangle(FreedomFighters,max_loc,(max_loc[0]+w,max_loc[1]+h),(0,0,255),2)
