techniques are compared to several AI-based compression models provided by and trained with the CompressAI toolbox using python. These different compression techniques are compared in compression ratio, multiple image similarity measures and, most importantly, the prediction accuracy from label-free models...
where X and Y are the two color images being compared, \(PC_m\) is the phase congruency at a given pixel, \(GM_m\) is the gradient magnitude at the pixel, and \(S_l\) and \(S_r\) are the similarity measures for the left and right images respectively. The sums are taken ove...
The system architecture consists of four main modules: preprocessing, feature extraction, feature reduction, and similarity measurement. Figure 1 presents the system’s architecture. Figure 1. System architecture. The system was developed using Python version 2.7.12, with the help of Google Colaborato...
Python is a programming language with high object-oriented capabilities. The compilation process can bring great convenience, and it is relatively quick to modify programs or debug errors. In addition to matrix calculations and data images, Python can create human–machine user interfaces and be ...
In this blog post I showed you how to compare two images using Python. To perform our comparison, we made use of the Mean Squared Error (MSE) and the Structural Similarity Index (SSIM) functions. While the MSE is substantially faster to compute, it has the major drawback of (1) being...
defined the utility of a biometric sample as the normalized difference between the sample’s mated similarity score and the mean of the sample’s non-mated similarity scores in a data set that contains two samples per finger instance [3]. More than two samples per instance were not available...
