Spatial-domain Convolution/deconvolution Transform
A new linear transform is deened for real valued functions which can be expanded in Taylor series. For an image which can be expressed by the Taylor expansion of a function, the new transform corresponds to convolution of the image with a point spread function. The point spread function must satisfy the condition that it's zero-th moment is non-zero and positive integer moments are nite. The fo...
متن کاملAn Efficient Spatial Domain Error Concealment
This paper presents an efficient spatial domain error concealment method for the forthcoming video coding standard H.264. In H.264, a frame is divided into 4× 4 blocks during encoding procedure. For natural image signal, the blocks are smoothly connected with each other. Based on this property, a linear smoothness constraint equation that describes the connection of lost block and its neighbori...
متن کاملEfficient Biometric Verification in Encrypted Domain
Biometric authentication over public networks leads to a variety of privacy issues that needs to be addressed before it can become popular. The primary concerns are that the biometrics might reveal more information than the identity itself, as well as provide the ability to track users over an extended period of time. In this paper, we propose an authentication protocol that alleviates these co...
متن کاملDomain Identification and Description Techniques
A system to be developed is expected to provide solution of a problem. After a careful identification of domains, an explicit, precise and well-engineered description is essential to develop an accurate solution providing system. Machine domain is formal while problem domain is informal. Description is like a platform for the developers to start and finish the development activities. Four princ...
متن کاملA Study on Spatial and Transform Domain
Digital Image Watermarking is used for copyright protection of digital information. With the widespread of internet, the intellectual properties are accessible and manipulated easily. It demanded to have different ways to protect data. Digital watermarking provides a viable and promising solution. In this paper, we have described about the three different watermarking techniques (LSB, DCT, DWT)...
