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

Introduction

The subject of this work is image compression with fractals. Today JPEG has become an industrial standard in image compression. Further researches are held in two areas, wavelet based compression and fractal image compression. The fractal scheme was introduced by Michael F Barnsley in the year 1945.His idea was that images could be compactly stored as iterated functions which led to the development of the IFS scheme which forms the basis of fractal image compression. Further work in this area was conducted by A.Jacquin, a stude ....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

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

Image-to-word transformation based on dividing and vector quantizing images with words
Abstract:
We propose a method to make a relationship between images and words. We adopt two processes in the method, one is a process to uniformly divide each image into sub-images with key words, and the other is a process to carry out vector quantization of the sub-images. These processes lead to results which show that each sub-image can be correlated to a set of words each of which is selected from words assigned to whole images. Original aspec ....etc
