Description: A general technique for the recovery of signicant
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 signicant 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: 基于Mean Shift的图像分割过程就是首先利用Mean Shift算法对图像中的像素进行聚类,即把收敛到同一点的起始点归为一类,然后把这一类的标号赋给这些起始点,同时把包含像素点太少的类去掉。然后,采用阈值化分割的方法对图像进行二值化处理。-Mean Shift Based on the process of image segmentation is the first to use the image Mean Shift algorithm for clustering of pixels, that is, to converge to the same point as a starting point to the category and then assigned to this type of labeling of these starting points, at the same time to contain too few pixels to remove the category. Then, using thresholding segmentation method of binary image processing. Platform: |

Shift算法具有更好的性能,向跟踪时间与经典算法大致相 .-The traditional Mean Shift tracking algorithm partitions uniformly the whole color space,leading to a great
number of void histogram bins,and is unable to represent accurately the color distribution of the object.To address
the problems,we present an improved algorithm.Firstly the object color is analyzed using a clustering algorithm,and
according to the clustering result the color space of the object is partitioned into subspaces by matrix factorization and
orthonormal transformation.Then a new color model is defined by considering the weighted number of pixels as well as
within—cluster distribution with Gaussian .and a novel measure iS derived to evaluate the similarity between the reference
color model and the candidate mode1.Finally an improved algorithm is proposed based on the color mode1.Experiments
show that the improved algorithm has better performance than and is computationally comparable to the conventional
mean shift algorithm. Platform: |
