Abstract

Gesture recognition is a vast topic of research in computer science. It deals with creating a system that can identify human gestures and use them for different applications. In gesture recognition, a camera is used to capture human body's motions which are sent to the computer for interpreting human body language. One of the major application areas of gesture recognition is automatic sign language recognition. In sign language motion of human body parts like hands and head are very important to consider. Whenever trajectories and movements are considered, tracking plays a vital role and is essential too. Tracking helps in recognizing the motion trajectories. This paper presents literature review on research and findings by researchers on different techniques and approaches of tracking.

Keywords

Abstract

Analog to digital converter is a fundamental component for digital processors since every signal which needs to be processed using digital algorithms requires the digital data. There are many different types of A/D converters are available but the sigma delta A/D converter has their unique advantage over others as they have only 10 to 15 percent analog components and rest are digital. This makes it good candidate when the A/D needs to integrate with the DSP in single chip, but the integration of two domains creates difficulty to evaluate the behavior of A/D using normal simulators hence special simulators called analog and mixed signal simulators are required in this paper we presented the detail simulation and analysis of sigma delta A/D using VHDLAMS.

Keywords

Sigma Delta A/D Converters, VHDLAMS.
