Survey over image thresholding techniques and quantitative performance evaluation
TLDR
40 selected thresholding methods from various categories are compared in the context of nondestructive testing applications as well as for document images, and the thresholding algorithms that perform uniformly better over nonde- structive testing and document image applications are identified.

Bosphorus Database for 3D Face Analysis
TLDR
A new 3D face database that includes a rich set of expressions, systematic variation of poses and different types of occlusions is presented, which can be a very valuable resource for development and evaluation of algorithms on face recognition under adverse conditions and facial expression analysis as well as for facial expression synthesis.

Statistical evaluation of image quality measures
TLDR
It was found that measures based on the phase spectrum, the multireso- lution distance or the HVS filtered mean square error are computa- tionally simple and are more responsive to coding artifacts. Expand
Spatio–Temporal Transform Based Video Hashing
TLDR
It is found that these hash functions are resistant to signal processing and transmission impairments, and therefore can be instrumental in building database search, broadcast monitoring and watermarking applications for video. Expand
Steganalysis using image quality metrics
TLDR
Simulation results with the chosen feature set and well-known watermarking and steganographic techniques indicate that the proposed approach is able with reasonable accuracy to distinguish between cover and stego images. Expand
Shape-based hand recognition
TLDR
Both the classification and the verification performances are found to be very satisfactory as it was shown that, at least for groups of about five hundred subjects, hand-based recognition is a viable secure access control scheme. Expand
Multiresolution face recognition
TLDR
This paper proposes a method to employ multiresolution analysis to decompose the image into its subbands, and aims to search for the subbands that are insensitive to the variations in expression and in illumination. Expand
Regression-based intensity estimation of facial action units
TLDR
This work proposes a novel AU intensity estimation scheme applied to 2D luminance and/or 3D surface geometry images and performs significantly better than the state-of-the-art method which is based on the margins of SVMs designed for AU detection. Expand
A comparative study of face landmarking techniques
TLDR
The purpose of this survey is to give an overview of landmarking algorithms and their progress over the last decade, categorize them and show comparative performance statistics of the state of the art. Expand
