In the early research, HSV color space is considered to be uniform with human's vision model. Along with the analysis of HSV space, we find the uniform is limited and propose a new quantization method, which is more reasonable to human's vision model. Without decreasing the retrieval performance, the scheme non-uniformly quantizes the color space into 36 bins. Because the quantization result has only 36 bins, the computational complexity is decreased effectively while the performance increases. Relevance feedback is an interactive technique in the process of CBIR.
在以前的研究中,一直认为HSV色彩空间与人的视觉感知是一致的,本文通过对HSV色彩空间非等间隔量化的研究,发现这种一致是有限的,通过对HSV色彩空间的分析,本文对相似色区域的划分提出了从视觉上更合理的不等间隔的量化方法,使其更符合人的主观视觉模型,并且在不降低检索性能的前提下,使色彩量化为36种颜色,有效地降低了算法复杂度,提高了检索效率。

In the paper, the author establish the evaluation system between the "two planing" based on the reintegrating and perfecting of the spatial planning system in our country and the reforming requirement to the sub-planning of spatial planing—the "two planing" from the change of precondition of the making of planning, through which to indicate the complicated contradictive relation between the " two planning ", to quantificationally appraise the present maturity degree and to guide the developing direction to the " two planning ". the author try to find out the two planning's reform direction and emphases in aftertime though out putting the evaluation system between the "two planing" into the sample city regional practice. In the end of this paper, the division and the collaboration mechanisms of the "two planing" have been discussed under the future perfect spatial planning system, also the division and the collaboration two strategies of the "two planing" based on current situation development of planning and the future perfect spatial planning system have been pointed out.
