近年来,由于气候与环境的变化及城市化进程的加快,一些与天气、气候等环境因素密切相关的疾病,如呼吸道疾病、心脑血管病的发病率呈逐年上升趋势。时值冬季,我们就来谈谈冬季的天气、气候与健康之间的关系。在冬季,人体的新陈代谢作用变缓,以尽可能地保持体力,但同时也降低了人体抵抗疾病的能力。事实的确如此,
In recent years, due to the change of climate and environment and the acceleration of urbanization, some diseases closely related to environmental factors such as weather and climate, such as respiratory diseases and cardiovascular and cerebrovascular diseases, have been increasing year by year. In winter, let’s talk about winter weather, the relationship between climate and health. In winter, the body’s metabolism slows to keep it as physical as possible, but it also reduces the body’s ability to fight disease. Indeed,

为了解决Mean Shift跟踪算法中目标模板只能从单一图像建立且很难更新问题,提出了一种结合改进的Mean Shift与增量式支持向量机的红外目标跟踪算法。首先,根据目标区域的灰度直方图对目标进行描述,然后采用标准Mean Shift搜索目标,结合子图图像矩特征进行二次搜索,再计算下一帧搜索的窗口大小,以解决目标尺寸明显变化时造成目标丢失的问题。同时,针对目标遮挡易导致跟踪失败的问题,引入机器学
