Image Segmentation by Bilayer Superpixel Grouping

2013 2nd IAPR Asian Conference on Pattern Recognition, 2013
The task of image segmentation is to group image pixels into visually meaningful objects. It has long been a challenging problem in computer vision and image processing. In this paper we address the segmentation as a super pixel grouping problem. We propose a novel graph-based segmentation framework which is able to integrate different cues from ...

SymmSLIC: Symmetry Aware Superpixel Segmentation

2017 IEEE International Conference on Computer Vision Workshops (ICCVW), 2017
Over-segmentation of an image into superpixels has become an useful tool for solving various problems in computer vision. Reflection symmetry is quite prevalent in both natural and man-made objects. Existing algorithms for estimating superpixels do not preserve the reflection symmetry of an object which leads to different sizes and shapes of ...

4D Light Field Superpixel and Segmentation

2017 IEEE Conference on Computer Vision and Pattern Recognition (CVPR), 2017
Superpixel segmentation of 2D image has been widely used in many computer vision tasks. However, limited to the Gaussian imaging principle, there is not a thorough segmentation solution to the ambiguity in defocus and occlusion boundary areas. In this paper, we consider the essential element of image pixel, i.e., rays in the light space and propose ...

Fast Superpixel Segmentation with Deep Features

2019
In this paper, we propose a superpixel segmentation method which utilizes extracted deep features along with the combination of color and position information of the pixels. It is observed that the results can be improved significantly using better initial seed points.

Hand segmentation with metric learning superpixels

2014 IEEE China Summit & International Conference on Signal and Information Processing (ChinaSIP), 2014
In this paper, we propose a novel method for hand segmentation. To improve the robustness to the wide range of hand appearances and illuminations, we segment the hand area with a superpixels based method instead of a general color model. With the exploitation of the distribution of hand pixels in color space, a distance metric learning stage is ...

Motion segmentation with occlusions on the superpixel graph

2009 IEEE 12th International Conference on Computer Vision Workshops, ICCV Workshops, 2009
We present a motion segmentation algorithm that partitions the image plane into disjoint regions based on their parametric motion. It relies on a finer partitioning of the image domain into regions of uniform photometric properties, with motion segments made of unions of such “superpixels.” We exploit recent advances in combinatorial graph optimization

Edge Adaptive Seeding for Superpixel Segmentation

2017
Finding a suitable seeding resolution when using superpixel segmentation methods is usually challenging. Different parts of the image contain different levels of clutter, resulting in an either too dense or too coarse segmentation. Since both possible solutions cause problems with respect to subsequent processing, we propose an edge adaptive seeding ...

Dynamic Random Walk for Superpixel Segmentation

2019
In this paper, we present a novel Random Walk model called Dynamic Random Walk (DRW) for superpixel segmentation. The proposed DRW adds a new type of node called dynamic node to enrich the features of labels and reduce redundant calculation. By greedily optimizing the Weighted Random Walk Entropy (WRWE), our DRW can consider the features of both seed ...
