Digital Still Camera Forensics

In many instances computer forensic practitioners come across digital photographs within an investigation. Examples include law enforcement examining computers for child pornography, intellectual property disputes involving proprietary digital images, or file recovery for individuals who have lost personal photos due to accidental deletion or electronic media corruption. More technical examples...

Fft Benchmarking for Digital Signal Processing Technologies

− An appropriate choice of the computing devices employed in digital signal processing applications requires to characterize and to compare various technologies, so that the best component in terms of cost and performance can be used in a given system design. In this paper, a benchmark strategy is presented to measure the performances of various types of digital signal processing devices. Altho...

IMAGE SENSORS and SIGNAL PROCESSING for DIGITAL STILL CAMERAS

Automatic White Balance for Digital Still Camera

A new algorithm of automatic white balance for electronic images has been developed. This algorithm uses hzzy logic rules for determinationi of the color parameters in order to minimize the color temperature difference of various light sources. This algorithm has been implemented in a newly designed electronic still camera, and resulted in highly improved image quality.

Digital Signal Processing Fundamentals

Recent advances in digital signal processing (DSP) technology make it easier for scientists to develop powerful personal computer-based data acquisition and analysis systems. This application note discusses DSP technology from a hardware, software, and application point of view. The Reduced Instruction Set Computer (RISC) architecture of the Texas Instruments (TI) TMS320C30 chip is used as an e...
