MAKING WEB APPLICATION PERFORMANCE EVALUATION QUESTIONNAIRE LECTURE USING PHP AND MYSQL PROGRAMMING LANGUAGE

Compression application program is a program used to reduce the size of data bits from the original image. To compress the data can be performed on text data, images, audio, and video. As of this writing to discuss the way of making the application method of image DCT-based JPEG compression using MATLAB 6.5. After designing the application to apply the test images used tools in matlab 6.5. DCT method is to use lossy compression techniques because no data were omitted when compressing the image. This method is done by eliminating high frequency components of the image that stores only low-frequency coefficients. Compression application program generated as expected in application design stage, although there are still shortages in some ways.
