A method for spatial-temporal denoising and demosaicking for noisy color filter array (CFA) video, the method including applying spatial-temporal CFA video denoising () to the CFA video in order to generate a denoised CFA, applying initial color demosaicking (CDM) () to the denoised CFA video in order to generate a demosaicked video, and applying spatial-temporal post-processing () to the demosaicked video in order to reduce CDM artifacts and CDM errors and enhance the quality of the video.

A biometric identification system () for identifying a person, the system () comprising: an image acquisition module () to capture a three-dimensional (3D) image of a palm of the person; a region of interest (ROI) extraction module () to extract a 3D subimage from the captured image; and a 3D features extraction module () to extract 3D palmprint features from the 3D subimage; wherein the extracted 3D palmprint features are compared to reference 3D palmprint features to verify the identity of the person.

Method and system for personal identification using 3D palmprint imaging

A method for identifying a person using their finger-joint print including the outer skin around the proximal interphalangeal joint of a finger, the method comprising: capturing () an image of the finger-joint print of the person; extracting () a region of interest (ROI) based on a local convexity property of the finger-joint print; extracting () features representing the orientation of the lines in a finger-joint print image from the ROI using an extended Gabor phase coding scheme and the extracted features are represented in competitive code maps; wherein angular distance between the competitive code maps is compared () with a reference set in a database to identify the person.
