FULL- REFERENCE METRIC FOR IMAGE QUALITY ASSESSMENT

Abstract


The quality of image is most important factor in image processing, to evaluate the quality of image various methods have been used. Proposed system defines one of the best methods in image quality assessment. Proposed system calculates the image quality assessment using normalized histogram. Sender send the image to the receiver, after receiving the image, receiver compare the image with senders image using normalized histogram. In proposed work, MGA transforms perform excellently for reference image reconstruction, have perfect perception of orientation, are computationally tractable, and are sparse and effective for image representation. MGA is utilized to decompose images and then extract features to mimic the multichannel structure of HVS. Additionally, MGA offers a series of transforms including wavelet, curvelet, bandelet, contourlet transform etc. These different types of  transforms are used to capture different types of image geometric information. Contrast Sensitivity Function(CSF) and Just Noticiable Difference(JND) isused to produce a noticeable variation in sensory experience. After calculating the normalized histogram of both the reference and distorted image, we are checking the quality of both the images.
