In recent years, the occurrence of large earthquakes is frequent all over the word. In the face of the inevitable natural disasters, the prediction of the earthquake is particularly important to avoid more loss of life and property. Many achievements in the field of predict earthquake from remote sensing images have been obtained in the last few decades. But the traditional prediction methods presented do have the limitations of can't forecast epicenter location accurately and automatically. In order to solve the problem, a new predicting earthquakes method based on extract the texture and emergence frequency of the earthquake cloud is proposed in this paper. First, strengthen the infrared cloud images. Second, extract the texture feature vector of each pixel. Then, classified those pixels and converted to several small suspected area. Finally, tracking the suspected area and estimate the possible location. The inversion experiment of Ludian earthquake show that this approach can forecast the seismic center feasible and accurately.
The algorithm of single image haze removal using dark channel prior has a good result on restoring hazy images and makes it clear. But the original algorithm has some disadvantages such as inaccurate estimation of atmospheric light and distortion of the sky region. From the perspective of the two problems referred previously, we propose a new method to estimate the transmission and atmosphere light. First, according to the characteristics of the sky region, we divide the sky region and get the accurate atmospheric light; then, in order to avoid the distortion of the sky, a controllable parameter K is introduced to the transmission. The experiment results show that the restored images acquired by the experiment have natural colors and clear details.
Infrared medical examination finds the diseases through scanning the overall human body temperature and obtaining the temperature anomalies of the corresponding parts with the infrared thermal equipment. In order to obtain the temperature anomalies and disease parts, Infrared Medical Image Visualization and Anomalies Analysis Method is proposed in this paper. Firstly, visualize the original data into a single channel gray image: secondly, turn the normalized gray image into a pseudo color image; thirdly, a method of background segmentation is taken to filter out background noise; fourthly, cluster those special pixels with the breadth-first search algorithm; lastly, mark the regions of the temperature anomalies or disease parts. The test is shown that it’s an efficient and accurate way to intuitively analyze and diagnose body disease parts through the temperature anomalies.
