Illumination Invariant Colour Recognition.

ABSTRACT The article describes a colour based recognition system with three novel features. Firstly, the proposed system can operate in environments where spectral characteristics of illumination change in both space and time. Secondly, bene ts in terms of speed and 

Software realisation of a colour image recognition system with an image normalisation stage
free download

ABSTRACT The task of pattern recognition can be greatly facilitated if position, rotation and size normalisation are incorporated within the pre-processing stage. Having obtained the required normalisation, then either feature extraction, template matching, artificial neural 

Colour-based object recognition

Summary This thesis studies the use of colour information for object recognition. A new representation for objects with multiple colours-the colour adjacency graph (CAG)-is proposed. Each node of the CAG represents a single chromatic component of the image 

Evaluating colour-based object recognition algorithms using the soil-47 database
free download

ABSTRACT In this paper, a new image set, called the Surrey Object Image Library (SOIL-47) is introduced, on which the performance of two colour-based object recognition methods is evaluated. The data was collected specifically for testing colour-based recognition 

The role of skin colour in face recognition

ABSTRACT People have better memory for faces from their own racial group than for faces from other races. It has been suggested that this own-race recognition advantage depends on an initial categorisation of faces into own and other race based on racial markers, resulting in 

Manipulation of colour and shape information and its consequence upon recognition and best-likeness judgments
free download

ABSTRACT Previous forays into the study of recognition have revealed an advantage for line- drawn and photographic shape caricatures of faces in reaction-time paradigms. When a presentationtime technique was used, photographs with enhanced colour intensity and 

Colour and luminance interact to improve pattern recognition
free download

ABSTRACT The authors have previously hypothesised that colour vision has evolved not only to encode colour per se but also, perhaps principally, to enhance luminance-based visual processing, so that for colour information to be fully effective, luminance as well as 

Performance evaluation of the multi-modal neighbourhood signature method for colourobject recognition
free download

ABSTRACT The proposed method represents object or image colour structure by features computed from neighbourhoods with multi-modal colour density function. Stable invariants are derived from modes of colour density that are robustly estimated by the mean shift 

Recognition of Cylindrical Objects Using Occluding Boundaries Obtained from Colour Based Segmentation.
free download

ABSTRACT This paper describes a method for model-based recognition of cylindrical objects from occluding boundaries obtained by computationally efficient colour segmentation of a 2D image. The models are invoked by combining geometric and colour features. 

Fast invariant recognition of colour images based on Triplet–Fourier–Gauss transform
free download

One of the main and interesting problems of informatics is the clarification of how human eye and brain recognize objects of real world. Practice shows that they successfully cope with this problem, recognizing objects in different locations, views, elimination and in different 

Face detection and recognition using colour sequential images
free download

Face detection and recognition, as a specific content of pattern recognition, has a wide range of applications in virtual reality, intelligent human machine interface, videophone systems and security systems, etc. A successful and applicable system for human face 

Real-time colour recognition for machine vision systems
free download

ABSTRACT It is impossible to collect more than a tiny proportion of all of the possible examples of a given hue, to form a training set for a machine that learns to discriminate colours. In view of this, it is argued that colour generalisation is essential. Three mechanisms for learning 

Human Object Recognition Using Colour and Depth Information from an RGB-D Kinect Sensor
free download

ABSTRACT Human object recognition and tracking is important in robotics and automation. The Kinect sensor and its SDK have provided a reliable human tracking solution where a constant line of sight is maintained. However, if the human object is lost from sight during 

Object Recognition Using Colour, Shape and Affine Invariant Ratios
free download

ABSTRACT This paper describes a spectral-spatial model (for colour object recognition) which exploits the shape, colour and position of regions on the surface of a rigid object in describing it. Given a model and test image (with colour constancy pre-processing) 

Forensic Textile Fibre Matching by Multiresolution Planning and Colour Space PatternRecognition.
free download

Colour is a key element in the discrimination and matching of textile fibres for forensic purposes. Two aspects of research aimed at developing an autcmated forensic textile fibre matching system by colour computer vision are outlined. The segnentation procedure is 

Face recognition using eigenfaces and the crcb colour space
free download

ABSTRACT Most research on face recognition has focused on using the grey-scale intensity images for recognition. This is sensitive to changing lighting conditions. Colour is increasingly being used as a method for overcoming this sensitivity to lighting. In this 

Colour Face Image Database for Skin Segmentation, Face Detection, Recognition and Tracking of Black Faces Under Real-Life Situations
free download

JA OJO, SA Adeniran ,International Journal of Image Processing (IJIP) ,cscjournals.org ABSTRACT This paper presents a new face database containing only black face images. It is designed to be used for benchmarking algorithms developed for skin segmentation, face detection and recognition under real life situations. The database contains coloured 

Real Time Single and Multiuser Gesture Recognition Based on Skin Colour and Optical Flow

ABSTRACT Gestural interfaces offer the potential for a natural and non-cumbersome human computer interaction. High gesture recognition rates for both recorded sequences and real time video streams have been achieved. However, real time gesture recognition still
