Robust Colour Image Segmentation
نویسنده
چکیده
In this paper, we present a new method for segmenting a colour image into homogeneous regions. This method uses the discriminant properties of the three perceptual colour attributes : the hue H, the saturation S and the value V. In a preliminary step, each pixel is classiied according to a chromaticity degree which characterises its belonging to a colour space zone whose chromatic components are meaningful. In a second step, we apply a segmentation algorithm based on a recursive directed region grower, and which provides a hierarchical scene representation. Two examples are given where an indoor scene and a subsea image are processed to yield uniform regions. We compare the results obtained by using the diierent chromatic/achromatic classiication methods described in this paper.

Colour consistency in light microscopy based histology is an increasingly important problem with the advent of Gigapixel digital slide scanners and automatic image analysis. This paper presents an evaluation of two novel colour normalisation approaches against the previously utilised method of linear normalisation in lαβ colourspace. These approaches map the colour distribution of an over/under...
متن کاملReal-Time Adaptive Colour Segmentation for the RoboCup Middle Size League
In order to detect objects using colour information, the mapping from points in colour space to the most likely object must be known. This work proposes an adaptive colour calibration based on the Bayes Theorem and chrominance histograms. Furthermore the object’s shape is considered resulting in a more robust classification. A randomised hough transform is employed for the ball. The lines of th...
متن کاملObject-Oriented Method for Automatic Extraction of Road from High Resolution Satellite Images
As the information carried in a high spatial resolution image is not represented by single pixels but by meaningful image objects, which include the association of multiple pixels and their mutual relations, the object based method has become one of the most commonly used strategies for the processing of high resolution imagery. This processing comprises two fundamental and critical steps towar...
