Image Comparison and Analysis Tool

Introduction

The Image Comparison and Analysis Tool is a user-friendly application designed to provide a suite of image processing and analysis features through a graphical user interface (GUI) built with Gradio. This tool allows users to perform various operations on images, such as comparing, blending, subtracting, and analyzing images for specific features like noise artifacts, text, signatures, and edges.

Features

Image Operations

• Resize Target to Match Reference: Resizes the target image to match the dimensions of the reference image.

• Add Images: Adds the pixel values of the target image to the reference image.

• Subtract Images: Subtracts the pixel values of the target image from the reference image.

• Blend Images: Blends the reference and target images together using a specified alpha value.

• Edge Detection on Reference: Applies an edge detection filter to the reference image.

• Histogram Comparison: Compares the histograms of the reference and target images and provides a difference metric.

Advanced Options

• Flip Operation Order: Flips the order of operations so that operations are performed as "Target Operation Reference" instead of the default "Reference Operation Target".

• View Alpha Layers: Displays the alpha (transparency) layers of the images.

• Use Alpha Layer Only for Operations: Performs operations using only the alpha layers of the images.

• Invert Reference/Target Image: Inverts the colors of the reference or target image before performing the primary operation.

• Save Inverted Images: Saves the inverted reference or target images to the specified output directory.

• Create Blank Reference/Target Image: Creates a blank (white) reference or target image matching the dimensions of the opposite image.
