Quantization


This involves representing the sampled data by a finite number of levels based on some criteria such as minimization of the quantizer distortion, which must be meaningful.

Quantizer design includes input (decision) levels and output (reconstruction) levels as well as number of levels. The decision can be enhanced by psychovisual or psychoacoustic perception.

Quantizers can be classified as memoryless (assumes each sample is quantized independently ....etc

Abstract
Detection of double joint photographic experts group (JPEG) compression is of great significance in the field of digital forensics. Some successful approaches have been presented for detecting double JPEG compression when the primary compression and the secondary compression have different quantization matrixes. However, when the primary compression and the secondary compression have the same quantization matrix, no detection method has been reported yet. In this paper, we present a method which can detect double JPEG compress ....etc

A 130nm CMOS to Minimize area and quantization noise in frequency synthesizer using offset PLL
ABSTRACT
 It achieves low-noise .
 OPLL highly suppresses the quantization noise from the delta-sigma modulator.
 It consumes low power by employing charge-recycling
technique in the sub-PLL.
 Synthesizer implemented in 0.13 ȗm
 CMOS process achieves 9 dB of noise reduction compared to a conventional PLL while consuming 3.2 mW of po ....etc

VOICE RECOGNITION AND VOICE GUIDANCE BASED GPS TURN-BY-TURN NAVIGATOR FOR BLIND WITH ULTRASONIC OBSTACLE AVOIDANCE



The main aim of the project is to design a navigator system for the blind based on GPS, voice recognition and ultrasonic sensor for obstacle detection. This advantage of this device is voice based announcement for easy navigation i.e. the user gets the voice which pronounces the directions he need to move to reach his destination. Here instead of the ....etc
