The image is considered similar and moved from the folder if hamming distance is less than a threshold set by user.

Hamming distance: comparing hashes with each other and count the number of different pixels.

Setting the color of each pixel to black if the NxN matrix value is above average, and to white otherwise Detect codes in the input image, and output the corners of detected rectangles: bool resultdetection bardet->detect (input, corners) decode This function first super-scales the image if it is smaller than threshold, sharpens the image and then binaries it by OTSU or local-binarization.

Next, import the source code you’ve download to your P圜harm IDE. Step 2: Import the project to your P圜harm IDE. First, download the given source code below and unzip the source code.

Calculating the mean of all color values These are the steps on how to run Document Scanner OpenCV Python With Source Code Step 1: Download the given source code below.Reducing size of each image to NxN pixels (set by user).

Perceptual hashing The script detects similar images based on a simple algorithm: OpenCV is a library written in C++ aimed to provide an infrastructure for computer vision and machine learning. Cleans similar or duplicate images from folder using perceptual image hashing with live preview How it works
