Image forensics of digital cameras by analysing image variations using Statistical Process Control

2009 7th International Conference on Information, Communications and Signal Processing (ICICS), 2009
In this paper, we propose the novel use of Statistical Process Control (SPC) as a tool for identifying anomalies in digital cameras, by analysing image variations. We apply SPC on six low-end cameras, and one mid-range camera. By plotting the mean distribution of image pixel data through control charts, we have been able to identify a clear distinction

Sparse Representation and Variational Methods in Retinal Image Processing

2010
Relations between different types of cameras used for retinal imaging were studied with the purpose of improving the quantitative precision of the imaging data (used for diagnostics and medical research). Based on the differences in visual quality and quantitative parameters, we designed analytical models of the effects that cameras introduce into the ...

New discretization of total variation functional for image processing tasks

Signal Processing: Image Communication, 2019
Abstract In this paper, a new discretization of total variation model is proposed to solve mathematical image problems. By using difference operators in the four directions (i.e. horizontal, vertical and two diagonal directions) an estimation of derivative amplitude is found.

Variational Approach Based Image Pre- Processing Techniques for Virtual Colonoscopy

2010
Colorectal cancer includes cancer of the colon, rectum, anus and appendix. Since it is largely preventable, it is extremely important to detect and treat the colorectal cancer in the earliest stage. Virtual colonoscopy is an emerging screening technique for colon cancer.
