Restoring the original image from blurred or degraded image due to motion blur, noise or camera misfocus has long been a challenging problem in digital imaging. Image restoration is thus a process of recovering the actual image from the degraded image. The purpose of the paper is to restore the blurred/degraded images using blind deconvolution algorithm with canny edge detector. The task of image deblurring is to deconvolute the degraded image with the point spread function (PSF) that describes the distortion. Firstly the original image is degraded using degradation model. It can be done by low pass filters like Gaussian filter or others to blur an image. The ringing effect at the edges of blurred image can be detected using Canny Edge Detection method. Blind deconvolution algorithm is applied to the blurred image where image recovery is performed with little or no prior knowledge of the degrading PSF. Also the penalized maximum likelihood Estimation Technique is used with blind deconvolution algorithm.Keywords

Content based image retrieval is a set of techniques for retrieving semantically relevant images from an image data based on automatically derived image features. In CBIR, Image are indexed by their visual content, such as color, texture and shapes. Further research has suggested that the usage of clustering technique of image retrieval. For this paper we compare Fuzzy Possiblistic C-Means clustering algorithm for retrieving the most similar images. In our experimental results shows that the modify Fuzzy Possiblistic Clustering Algorithm is better retrieval.Keywords

Computer hallucination, unlike humans, still has not fully acquired the facility to categories a person’s age group from an image of the person’s face. Successful gender and age classification could be used to boot the performance of face recognition system. Fuzzy models have been used and analyzed in this work to achieve the desired results. The concept of fuzzy lattice neural model is introduced and is applied to classify the age group of a person from the gray scale facial image. Next the fuzzy lattice relation model is constructed and is used to classify the age group of a person. Then the fuzzy lattice neural model is applied to segment an aerial gray scale image.
