Hyperspectral Image Acquisition and Calibration with Application to Skin Detection Systems
… In our e orts to build a hyperspectral skin detection system, several new problems were identified that had not previously been adequately addressed, suggesting that routine use of spectral imaging techniques in terrestrial (earth-based) applications is non-trivial. Previously …

Cardiac Signals: Remote Measurement and Applications
… magnification. We have extracted signals from skin patches and then used frequency domain correlation to filter out non-cardiac signals. We have developed a novel entropy based method to automatically select skin patches from face. We report beat-to-beat accuracy of remote PPG (rPPG) in …

Camera-based Recovery of Cardiovascular Signals from Unconstrained Face Videos Using an Attention Network
… in part from the incorporation of a robust skin-detection module into the overall imaging-based photoplethysmography (iPPG) framework. We present extensive experimental results using the challenging UBFC-Phys dataset and the well-known COHFACE dataset. The source code is available at …

Sequential Recognition of Manipulation Actions Using Superpixel Group Mining
… representation approaches such as object detection and human body part detection, which contain expensive work of object and human annotations. Meanwhile, the object transformation information has not been considered comprehensively.<br/><br/>This thesis proposes a method for manipulation …

Digital Image Processing via Combination of Low-Level and High-Level Approaches.
… organised in three parts: Colour Edge and Face Detection; Hand motion detection; Hand Gesture Detection and Medical Image Processing. II In Colour Edge Detection, two new images G-image and R-image are built through colour space transform, after that, the two edges extracted from G-image and …

Automatic human face detection in color images
Automatic human face detection in digital image has been an active area of research over the past decade. Among its numerous applications, face detection plays a key role in face recognition system for biometric personal identification, face tracking for intelligent human computer interface (HCI), …

Color Invariant Skin Segmentation
… the problem of automatically detecting human skin in images without reliance on color information. Unlike previous methods, we present a new approach that performs well in the absence of such information. A key aspect of the work is that color-space augmentation is applied strategically during …

Robust facial expression recognition in the presence of rotation and partial occlusion
This research proposes an approach to recognizing facial expressions in the presence of rotations and partial occlusions of the face. The research is in the context of automatic machine translation of South African Sign Language (SASL) to English. The proposed method is able to accurately recognize …
