Conformal Mapping-Based Image Processing: Theory and Applications

Conformal Mapping and its Applications

Conformal (Same form or shape) mapping is an important technique used in complex analysis and has many applications in different physical situations.If the function is harmonic (ie it satisfies Laplace’s equation∇f = 0 )then the transformation of such functions via conformal mapping is also harmonic. So equations pertaining to any field that can be represented by a potential function (all conse...

Applications of Complex-Logarithmic Conformal Mapping in Still Image Coding

This paper evaluates the performance of an image compression system based upon the complex logarithmic conformal mapping. A staple in the robotics and visual systems fields, our attempts were to investigate the application of this algorithm in the field of image compression. The characteristics predisposed to the log sensor include a foveal region centered around the focal point which generates...

SVD Based Image Processing Applications:

Singular Value Decomposition (SVD) has recently emerged as a new paradigm for processing different types of images. SVD is an attractive algebraic transform for image processing applications. The paper proposes an experimental survey for the SVD as an efficient transform in image processing applications. Despite the well-known fact that SVD offers attractive properties in imaging, the exploring...

Content-Based Image Retrieval: Theory and Applications

Advances in data storage and image acquisition technologies have enabled the creation of large image datasets. In this scenario, it is necessary to develop appropriate information systems to efficiently manage these collections. The commonest approaches use the so-called Content-Based Image Retrieval (CBIR) systems. Basically, these systems try to retrieve images similar to a user-defined speci...
