Slt,

Est ce que quelqu’un peut me dire ce que donne ca (sur les fichier dans la dropbox ? :

from skimage.metrics import structural_similarity
import cv2
import numpy as np
 
first = cv2.imread('clownfish_1.jpeg')
second = cv2.imread('clownfish_2.jpeg')
 
# Convert images to grayscale
first_gray = cv2.cvtColor(first, cv2.COLOR_BGR2GRAY)
second_gray = cv2.cvtColor(second, cv2.COLOR_BGR2GRAY)
 
# Compute SSIM between two images
score, diff = structural_similarity(first_gray, second_gray, full=True)
print("Similarity Score: {:.3f}%".format(score * 100))
 
# The diff image contains the actual image differences between the two images
# and is represented as a floating point data type so we must convert the array 
# to 8-bit unsigned integers in the range [0,255] before we can use it with OpenCV
diff = (diff * 255).astype("uint8")
 
# Threshold the difference image, followed by finding contours to
# obtain the regions that differ between the two images
thresh = cv2.threshold(diff, 0, 255, cv2.THRESH_BINARY_INV | cv2.THRESH_OTSU)[1]
contours = cv2.findContours(thresh, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE)
contours = contours[0] if len(contours) == 2 else contours[1]
 
# Highlight differences
mask = np.zeros(first.shape, dtype='uint8')
filled = second.copy()
 
for c in contours:
    area = cv2.contourArea(c)
    if area > 100:
        x,y,w,h = cv2.boundingRect(c)
        cv2.rectangle(first, (x, y), (x + w, y + h), (36,255,12), 2)
        cv2.rectangle(second, (x, y), (x + w, y + h), (36,255,12), 2)
        cv2.drawContours(mask, [c], 0, (0,255,0), -1)
        cv2.drawContours(filled, [c], 0, (0,255,0), -1)
 
cv2.imshow('first', first)
cv2.imshow('second', second)
cv2.imshow('diff', diff)
cv2.imshow('mask', mask)
cv2.imshow('filled', filled)
cv2.waitKey()
 

 ( je veux faire un script pour me gerer du hdr dans une data base, mais je cherche comment detecter les images similaire, j’ai lance un fil sur gid hup mais je dois pas etre claire il propose une cles de hash par fichier !)

D’apres MikeRobinson :

convert -append `counter=0; for x in in-*; do if [[ $(($counter % 2)) == 0 ]]; then echo $x; fi; counter=$((counter + 1)); done` out.jpg 

Pour le script avec imagemagick, y a des script pour assemblee les images d’etoiles ! Mais peut etre quelqu’un connait mieux ?

Merci
