A comparative evaluation of interactive segmentation algorithms [PDF]
, 2010 In this paper we present a comparative evaluation of four popular interactive segmentation algorithms. The evaluation was carried out as a series of user-experiments, in which participants were tasked with extracting 100 objects from a common dataset: 25

Region-based segmentation of images using syntactic visual features [PDF]
, 2005 This paper presents a robust and efficient method for segmentation of images into large regions that reflect the real world objects present in the scene. We propose an extension to the well known Recursive Shortest Spanning Tree (RSST) algorithm based on

Picture Segmentation by a Tree Traversal Algorithm
Journal of the ACM, 1976 In the past, picture segmentation has been performed by merging small primitive regions or by recursively splitting the whole picture. This paper combines the two approaches with significant increase in processing speed while maintaining small memory requirements. The data structure is described in detail and examples of implementations are given.

Hierarchical Models for Image Segmentation: from Color to Texture [PDF]
, 2008 Segmentation is a low-level processing aimed at the partition of an image in disjoint regions, each one homogeneous with respect to some properties like intensity, texture, shape, etc.

Volumetric texture segmentation by discriminant feature selection and multiresolution classification [PDF]
, 2007 In this paper, a multiresolution volumetric texture segmentation (M-VTS) algorithm is presented. The method extracts textural measurements from the Fourier domain of the data via subband filtering using an orientation pyramid (Wilson and Spann, 1988).
