Image Inpainting Method based on Evolutionary Algorithm
This paper proposes an image inpainting method based on evolutionary algorithm. The main idea of the proposed method is to restore the structure information and texture information separately. The structure information is extracted from the damaged image which is presented by several contour lines. An optimizing method based on evolutionary algorithm is proposed to analyze the structure informa...
متن کاملImage Retrieval Method Based on Entropy and Fractal Coding
In content-based image retrieval system, describing and extracting image’s feature is a key question. An image can be characterized by its fractal codes, and fractal codes can be used as the image’s feature to retrieve the images effectively. This paper proposes a novel image retrieval method using information entropy and fractal coding. First, each image in the database is classified by comput...
متن کاملImage Compression Method Based on QR-Wavelet Transformation
In this paper, a procedure is reported that discuss how linear algebra can be used in image compression. The basic idea is that each image can be represented as a matrix. We apply linear algebra (QR factorization and wavelet transformation algorithms) on this matrix and get a reduced matrix out such that the image corresponding to this reduced matrix requires much less storage space than th...
متن کاملImprovement on Fractal Image Coding Based on the Difference Image
In this paper, we propose an enhanced Fractal Image Compression (FIC) approach. In this method, the original image is represented by a provisional image and a difference image, which records the difference between the original and provisional image. With the less number of domain blocks required to do the best match search, the encoding time can be reduced by about 30% with a tolerance loss in ...
متن کاملFractal-Based Techniques for a Generalized Image Coding Method
This paper presents a new generalized image block coding algorithm which covers fractal techniques, block transform techniques, and vector quantization as its special cases. The coding is performed by approximating each image block with a linear combination of a series of (not necessarily orthogonal) blocks selected from a pool of basis blocks. This pool is made up of (1) a set of xed basis blo...
