On Fingerprinting Images for Recognition
نویسندگان
چکیده
A central task in multimedia systems is image management (storage and retrieval). As information is disseminated across vast networks, such as the Internet, methods of locating authored media are desirable. Digital watermarks provide a means to embed copyright and other information for identification and tracking. However, many watermarking techniques are vulnerable to distortion. We provide a means to identify images based on salient features within an image; a “fingerprint” that survives affine distortions and can be used to recognize images.

Face Recognition in Thermal Images based on Sparse Classifier
Despite recent advances in face recognition systems, they suffer from serious problems because of the extensive types of changes in human face (changes like light, glasses, head tilt, different emotional modes). Each one of these factors can significantly reduce the face recognition accuracy. Several methods have been proposed by researchers to overcome these problems. Nonetheless, in recent ye...
متن کاملIdentification of Printing Paper Based on Texture Using Gabor Filters and Local Binary Patterns
There are many causes of deformation in an image and one of which during its acquisition to a digital image. The deformation takes different forms or causes different effects on the acquired image comparing with the original image including poor resolution, shear, noise, variation in the intensity and etc. A paper scanned by a scanner is a good example of possible deformation in images. Consequ...

متن کاملDisguised Face Recognition by Using Local Phase Quantization and Singular Value Decomposition
Disguised face recognition is a major challenge in the field of face recognition which has been taken less attention. Therefore, in this paper a disguised face recognition algorithm based on Local Phase Quantization (LPQ) method and Singular Value Decomposition (SVD) is presented which deals with two main challenges. The first challenge is when an individual intentionally alters the appearance ...
متن کاملA New Fast and Efficient HMM-Based Face Recognition System Using a 7-State HMM Along With SVD Coefficients
In this paper, a new Hidden Markov Model (HMM)-based face recognition system is proposed. As a novel point despite of five-state HMM used in pervious researches, we used 7-state HMM to cover more details. Indeed we add two new face regions, eyebrows and chin, to the model. As another novel point, we used a small number of quantized Singular Values Decomposition (SVD) coefficients as feature...
