Super resolution is a technique which is used to enhance the visual quality of a sequence of low resolution image by constructing a single high resolution image. This paper is interested in acquiring the automatic number plate recognition system from the traffic surveillance video. The proposed system detects the number plate of a vehicle from video input and then performs the super resolution technique. Applying the Optical Character Recognition Technique it acquires the text from the super resolution image of vehicle number plate by means it compares with the RTO database and then it display the details of the vehicle such as owners name, vehicle registration etc.

The wide spread of the Internet increases the availability of all digital data such as image, audio and video to the publics. Digital watermarking is introduced to provide the security, data authentication and copyright to the digital data. This paper provides the basics of watermarking techniques, various applications; attacks carried in watermarking and detail study of reversible watermarking technique. One of the important techniques in watermarking is a reversible watermarking [52] technique. Reversible watermarking strengthens the ownership of the digital data and also supports to recover the original data from the watermarked digital data.
