Image-compressors Performance Evaluation Based on Power Measurement
نویسندگان
چکیده
The criteria applied on the choice of the compression algorithm is generally based on distortion, compression rate, processing time and hardware limitation. On most cases, the energy expenditure is not considered, however, in some applications, the energy expenditure is a good parameter for choosing the algorithms (E.g. embedded systems that apply the use of batteries). Thus, this article proposes an analysis scheme for algorithm’s energy expenditure and a focused assessment based on the scope of image compression. The scheme will allow the choice of image compression algorithms by using the energy expenditure as a metric. The most common image-compression algorithms will be analysed and the results will be demonstrated through three-dimensional curves (rate-distortion-energy). Keywords— Image-compression, Energy-measurement, Rate-distortion Theory, Satellite Communication, Greencommunication.

Performance evaluation of block-based copy- move image forgery detection algorithms
Copy-move forgery is a particular type of distortion where a part or portions of one image is/are copied to other parts of the same image. This type of manipulation is done to hide a particular part of the image or to copy one or more objects into the same image. There are several methods for detecting copy-move forgery, including block-based and key point-based methods. In this paper, a method...
