Suspect Multifocus Image Fusion Based on Sparse Denoising Autoencoder Neural Network for Police Multimodal Big Data Analysis

Scientific Programming, Volume 2021, Issue 1, 2021., 2021
In recent years, the success rate of solving major criminal cases through big data has been greatly improved. The analysis of multimodal big data plays a key role in the detection of suspects. However, the traditional multiexposure image fusion methods have low efficiency and are largely time‐consuming due to the artifact effect in the image edge and ...

A grid-line suppression technique based on the nonsubsampled contourlet transform in digital radiography

Nuclear Engineering and Technology, 2023
In radiography, an antiscatter grid is a well-known device for eliminating unexpected x-ray scatter. We investigate a new stationary grid artifact suppression method based on a nonsubsampled contourlet transform (NSCT) incorporated with Gaussian band ...
