The accurate thermal image segmentation becomes extremely challenging in the complex background conditions, especially in the circumstances that the foreground target and the background are very similar. The paper uses the Gaussian mixture model (GMM) for the rough segmentation in the temporal domain to solve the problem of complex background, then for the fine segmentation in the spatial domain by...
At the inception of an ageing society in China, the issue of adding elevators to old residential building has attracted more and more attentions and become a pressing social problem. The paper focuses on some typical zones or buildings in different phases of adding elevators to old residential ones in Guangzhou, based on the approach that it combines quantitative analysis and qualitative analysis...
As China is becoming an ageing society, the issue of adding elevators to existing residential building is attracting more and more attention of the aged people which almost becomes a social problem. Based on the approach that combines quantitative analysis and qualitative analysis, some typical districts or buildings in Guangzhou that are in different phases of adding elevators to existing residential...
Based on the complexity and randomness of the infrared image degradation factors, and integrates the strong de-noising features of multi-scale morphological wavelet and the salient problem solving features of Hopfield neural network in optimization, this paper presents a new algorithm for infrared degraded image restoration. The algorithm takes advantage of the continuous recycle between "multi-scale...
Infrared image enhancement is a research focus as well as one of the difficulties in the field of information processing. Rough sets theory is a new mathematical tool to solve the issue of ambiguity and uncertainty. Curvelet transform develops from wavelet transform and has noticeable effect in denoising and signal enhancing. Based on the features of infrared image and human visual properties and...
As the dynamic range of the targets in X-ray images of feet is wide, and the overlapping interval of the background gray value and the target is large, this article comes up with a bone-image segmentation method in X-ray pictures of feet. First of all, composite enhancement will be applied, then the distribution features of target will be exploited to carry out a dynamic partition, finally density...
