FPGA Implementation of Increased Video Quality Using Tone Adjustment
نویسندگان
چکیده
The quality of video increased by the different enhancement techniques. In this paper we propose a video quality increasing technique by using tone adjustment. The human eye is very sensitive and very fascinating. The better quality video is proposed for human eyes. The quality of video cameras in ATMs, Shopping malls, and other heavy traffic areas is very poor. The increase of video quality from these low quality video cameras will be benefitted for the human life applications. This technique is implemented in Field programmable gate arrays vertex 5 family, and HSV transform algorithm is applied to the video frames which finally gets the high quality video out. Implemented with verilog language.

متن کاملFPGA Based Implementation of Video Denoising Using Warped Filter
Noise in video signal plays a major problem in most of the communication systems. Video denoising is the process of removing noise from the video signal. In order to increase compression effectiveness and improve subjective quality of video sequences video denoising process using Warped Filter is done. Warped Filter is an all pass filter; it is widely used for various video and audio processing...
متن کاملFPGA Implementation of a Hammerstein Based Digital Predistorter for Linearizing RF Power Amplifiers with Memory Effects
Power amplifiers (PAs) are inherently nonlinear elements and digital predistortion is a highly cost-effective approach to linearize them. Although most existing architectures assume that the PA has a memoryless nonlinearity, memory effects of the PAs in many applications ,such as wideband code-division multiple access (WCDMA) or orthogonal frequency-division multiplexing (OFDM), can no longer b...
