Unsupervised over-segmentation of an image into super-pixels is a common preprocessing step for image parsing algorithms. Superpixels are used as both regions of support for feature vectors and as a starting point for the final segmentation. Recent algorithms that construct superpixels that conform to a regular grid (or superpixel lattice) have used greedy solutions. In this paper we show that we...
Unsupervised over-segmentation of an image into super-pixels is a common preprocessing step for image parsing algorithms. Superpixels are used as both regions of support for feature vectors and as a starting point for the final segmentation. In this paper we investigate incorporating a priori information into superpixel segmentations. We learn a probabilistic model that describes the spatial density...
This paper presents a survey of the research carried out to date in the area of computer-based deformable modelling. Due to their cross-disciplinary nature, deformable modelling techniques have been the subject of vigorous research over the past three decades and have found numerous applications in the fields of machine vision (image analysis, image segmentation, image matching, and motion tracking),...
