Evaluating a colour morphological scale-space
نویسندگان
چکیده
Scale-spaces are usually associated with the diffusion equation operating on greyscale images. This paper presents a scale-space that is based on graph morphology and works in colour. The system is shown to be a natural extension of the existing greyscale graph-morphology scale-spaces. The system is evaluated by comparing it to a specially collected database of ground-truth images created by human subjects.

Ten colour emotional scales, namely, "Warm Cool", "Active-Passive", "Like-Dislike", "Clean-Dirty", "Fresh-Stale", "Modern-Classical", "Heavy-Light", "Hard- Soft", "Tense-Relaxed", and "Masculine-Feminine"are investigated for single-colour stimuli in CIELAB colour space within a psychophysical experiment by forty observers. The relationships between Iranian colour emotional responses and CIELAB ...
متن کاملColour Morphological Scale-Spaces for Image Segmentation
Morphological scale-spaces have become an important tool for analysing greyscale images. However, their extension to colour images has proven elusive until recently. In this paper an original evaluation of two recently proposed colour sieves is presented, both algorithmically and in terms of their computational and segmentation performance. A new colour sieve structure is also proposed, motivat...

متن کاملFuzzy mathematical morphology and its applications to colour image processing
In image analysis and pattern recognition fuzzy sets play the role of a good model for segmentation and classifications tasks when the regions and the classes cannot be strictly defined. One of the most widely used fuzzy approaches in image processing is fuzzy mathematical morphology because of the underlaying structure of complete lattices. Thus, mathematical morphology is used mainly in proce...
متن کاملMathematical Morphology in the L*a*b* Colour Space
The use of mathematical morphology in the L*a*b* colour space is discussed. Initially, a description of the characteristics of the L*a*b* space and a comparison to the HLS space are given. This is followed by a theoretical demonstration of the use of weighting functions to impose a complete order on a vector space. Various colour weighting functions are considered, and one based on a model of a...
