Proposed System:

In the recent years of image processing application of super resolution technique will increases a resolution day by day in lot of application, here this paper presents a Traffic controlling and monitoring through CCTV modules. In this CCTV based super resolution of Bi-cubic interpolation will not get the clarity in vehicle motion pictures at moving time. So this paper proposed this work with Interpolation such as Bi-Cubic method based Vertical and Horizontal Interpolation at taken the image of low resolution to interpolate to High resolution (1600×1600) pixel size.

As previously described, we assume LR image is a part of HR image. The proposed method needs to keep information of the LR image to reconstruct HR image for real time hardware processing. We propose algorithm based on Bi-cubic Interpolation to minimize the processing time but at the same time, to improve the reconstructed image quality as well. Our proposed method named overlapping bi-cubic interpolation updates the different new LR image with the original LR image to HR image.

The demand of the digital image processing technology from the social different domain growing at present day by day, some complex and effective algorithms of imagery processing related domain have been proposed. Usually, there are mainly two methods [1] to raise the imagery processing speed. First, carry on the optimization to the imagery processing algorithm. Simplifies the algorithm to raise the running speed of the algorithm, but the precision is very difficult to guarantee. Second, change the way to realize the algorithm. Considered the convenience and the cost, the imagery processing algorithm is realized generally with the form of software programming. The processing speed meets the timely need difficulty, because of standard serial processing method. The imagery processing speed can be raised, and the high speed [2] requirements can be met by the way of the software and hardware design for the algorithm which is simple structure, large quantity data and parallel character. FPGA, which is programmable logical component, not only has the characteristic of big scale, high integration rate and high reliable as ASIC, but also maintained the characteristic of short design cycle, lowly development invested and high flexibility as PLD. The central processors (CPU), the multiplier, the digital processor (DSP)[3] have been integrated in new generation FPGA. DSP are unable to compare with the hardware parallel processing and the stream line operation of FPGA. Therefore the application of FPGA in the digital image processing domain is quite ideal choice.
