Large multimedia-based applications need that academics find a more effective approach to use images in their apps as image data continues to grow. Image quality evaluation is crucial in image processing systems, especially when images are compressed for transmission. Because of the blocking effect that co-efficient quantification causes during image compression, the decompressed image has poor quality. The coefficient quantification of blocking effect removes high frequency component in the image, consecutively results in discontinuous leaps and reduces the quality of the image. Generally, the objective function is used to perform optimization on complex image processing task. Compression artefacts, noise, and designed linear or non-linear degradations in compressed images. To recover linear and nonlinear distortion from distorted images, image de-blocking techniques are applied. Deblocking techniques accepted by police and vigilance division to improve valuable evidences via ruined pictures of observations. An ordinary encoding and decoding quality characteristic of most digital images is the neighboring pixels that are related and subsequently extracts the unwanted disturbances. Our primary goal is to identify the less correlated representation of the digital photos through our research. There are three steps in our proposed approach, step 1 is the statistical feature removal using curvelet transform, then step 2 is the down-sampling of the image with blocking effect artefacts, finally step 3 is the usage of Quality Defined Convolutional Neural Network (QD-CNN) for the removal of blocking effect artefacts then finally the performance validation is carried out using quality assessment.
