    ABSTRACT: The objective of this paper is to implement the concept of wavelet based image compression to gray scale images using different techniques. The techniques involved in the comparison process are EZW and WDR. These techniques are more efficient and provide a better quality in the image. In compression, wavelets have shown a good adaptability to a wide range of data, while being of reasonable complexity. Wavelet difference reduction (WDR) has recently been proposed as a method for efficient embedded image coding. This method retains all of the important features like low complexity, region of interest, embeddedness, and progressive SNR. The above techniques have been successfully used in many applications. The techniques are compared by using the performance parameters PSNR and MSE. Images obtained with those techniques yield very good results.

    ABSTRACT: The objective of this paper is to implement the concept of wavelet based image compression to gray scale images using different techniques. The techniques involved in the comparison process are SPIHT, EZW and SOFM. These techniques are more efficient and provide a better quality in the image. In compression, wavelets have shown a good adaptability to a wide range of data, while being of reasonable complexity. This paper focuses important features of wavelet transform in compression of still images, including the extent to which the quality of image is degraded by the process of wavelet compression and decompression. The above techniques have been successfully used in many applications. The techniques are compared by using the performance parameters PSNR and MSE. Images obtained with those techniques yield very good results.

    ABSTRACT: The objective of the paper is to compare the different Wavelet based Image Compression algorithms. SPIHT, WDR, and ASWDR algorithm are involved in the comparison process. These are some recent algorithms, which produce some lowest errors per compression rate and highest perceptual quality. Finally, the results are compared using all the above algorithms.

    ABSTRACT: In this paper, we proposed a method to rank the professional colleges. Ranking the colleges is a mandatory process for the sake of students, to identify the best college in each discipline. We employ the fuzzy repertory table (FRT) technique to acquire the necessary domain knowledge of colleges from which the ranking is made. A sample of 4 colleges is taken into consideration and accessing similarity is made over it. Distinction matrix is created based on the similarities of colleges from which the ranking has been made.

    ABSTRACT: The lifetime of a product is dependent on its maintainability. It is proved that a lot of cost spent towards maintainability. Researchers find it as a difficult task to measure and improve software maintainability. Here we proposed a risk based approach to improve software maintainability. Risk based approach accounts the probability of failure of a portion of code as determined by its complexity. Four products with different functionalities are taken into consideration and its risk prone areas in the code are identified. A set of six metrics with its threshold values are used to locate the highly risked areas of a code. Suitable changes are recommended to these highly risked codes to improve software maintainability.

    ABSTRACT: Engineering Institutions in our country has increased a lot. Ranking the colleges is a mandatory process for the benefit of students, to identify the best college in each discipline. In this paper, we proposed a method to rank the professional colleges. We employ the fuzzy repertory table (FRT) technique to acquire the necessary domain knowledge of engineering colleges from which the ranking is made. A sample of 4 engineering colleges is taken into consideration and accessing similarity is made over it. Distinction matrix is created based on the similarities of colleges from which the ranking has been made. Index Terms: Fuzzy Repertory Table, Trapezoid Number, Repertory Grid, Distinction Matrix.
