Description: A general technique for the recovery of signi cant
image features is presented. The technique is based on
the mean shift algorithm, a simple nonparametric pro-
cedure for estimating density gradients. Drawbacks of
the current methods (including robust clustering) are
avoided. Feature space of any nature can be processed,
and as an example, color image segmentation is dis-
cussed. The segmentation is completely autonomous,
only its class is chosen by the user. Thus, the same
program can produce a high quality edge image, or pro-
vide, by extracting all the signi cant colors, a prepro-
cessor for content-based query systems. A 512 512
color image is analyzed in less than 10 seconds on a
standard workstation. Gray level images are handled
as color images having only the lightness coordinate-A general technique for the recovery of sig ni cannot image features is presented.

Description: 本文提出一种基于改进图模型的自适应道路跟踪算法,利用基于边缘置信度的均值偏移
算法,将图像划分为具有准确边界的若干同质区域,以这些区域为结点构建改进图模型,然后根据道路/非路模型统计信息,采用
Graph Cut 方法获得最终的二值图。该算法将Graph Cut 和均值偏移方法有效融合,以克服各自缺点,并通过道路/非路模型自更
新使得该算法可有效适应室外环境下复杂场景变化。-Two dimension road following is a crucial task of vision navigation for mobile robots. Because road
environments are usually complex, robust and continuous road following based on two-dimension image sequence
is still a challenging task. This paper proposes a self-adaptive road following algorithm based on an improved
graph model. Firstly, the mean shift algorithm embedded with edge confidence is used to partition the images into
homogenous regions with precise boundary, and an improved graph model is constructed with these regions. Platform: |

Description: 基于纹理和边缘方向特征融合的目标跟踪程序代码，是基于mean shift框架的-This paper proposes a powerful and robust local descriptor,called textureorientation
descriptor(TOD). TOD consists of two components: texture and
orientation. Considering that the human shape shows more short, fragmentary
and vertical edges, the proposed TOD descriptor encodes the spatial information
of pedestrian image. We combine the proposed TOD representation
model with mean shift framework to perform pedestrian tracking. Results
from experiments show the improved performance of the proposed algorithm,
in the scenarios of heavy occlusions, illumination variations and similar
objects interference, when compared with the other descriptors based trackers. Platform: |

Description: 这是一个很好的演示展示了均值漂移图像像素聚类思想的作品。虽然这段代码还没有实现多分辨率或进一步的均值漂移聚类的图像分割,它实现了核心的均值漂移算法.该算法是PAMI论文”Mean shift: a robust approach toward feature space analysis", 在2002提出的。
-This is a good demo of showing how the mean shift idea works for image pixel clustering. Although this code has not implemented mean shift multi-resolution clustering or further image segmentation, it implements the core mean shift algorithm introduced in the PAMI paper "Mean shift: a robust approach toward feature space analysis", 2002.
