In this paper, spatial neighboring pixels are used to deal with blocking and ringing artifacts while temporal neighboring pixels are utilized to remove mosquito and flickering artifacts. To avoid the blurring effect of linear filters, a fuzzy filter is implemented. Fuzzy filter is a specific case of bilateral filters [15], [16]. Fuzzy filters help denoising the artifacts while retaining the sha...
The region of image compression since it is applicable to various fields of image processing. The key goal of compression is to cut back the space for storage and decrease the transmission cost and maintain the visual quality of image. This paper presents fundamental approach for analysis and evaluating the image compression techniques. This paper describes the many techniques which can be used...
The overall objective of this paper is to review various image compression techniques. Image compression has become very important tool in digital image processing. The main objective of the compression is to reduce the amount or unwanted data while retaining the information in the image. The goal behind is to save the amount of memory required to save the image(s) or to utilize network bandwid...
The rapid uptake and increased complexity of mobile phones has provided an unprecedented platform for the penetration of mobile services. Among these, mobile entertainment is composed of a variety of services such as ringing tones, games, gambling, and so on. Games are predicted to replace ringing tones as the main driver of mobile entertainment. This chapter contributes to the development of t...
Abstract—The main topic of this paper are the EMI reduction problems in high voltage power converters with 6.5 kV IGBTs. The generation process of electromagnetic interference is briefly analyzed, some EMI reduction methods are introduced. Theoretical analysis, calculation and experimental results of choosing the snubber circuit for minimization of parasitic ringing are described. The effect of...
Using global contrast enhancement, low contrast image can be improved in its quality globally. The enhanced output image, with such type of enhancement, may not have the noise and ringing artifacts. However, it may have over-exposure on some parts of the image and under-exposure on some other parts of the image when too high contrast gain occurs. Besides these, the enhanced output image may lac...
