【摘要】 对于一幅图像,人的感知和理解是主观性的。图像理解是研究用计算机系统解释图像,实现类似人类视觉系统理解外部世界的一门科学。在图像理解的基础上进行图像情感语义的提取,希望计算机用语义的方式来表达对一个图像的理解并引起相对应的情感反应,以此来驱动特征人脸产生表情,对于人脸动画的研究具有重要意义。本文着重处理室外场景图像特别是天气图像的理解,首先应用颜色聚类的方法将图像分为两个主要的部分,然后将对应的颜色特征输入到已经学习好的神经网络中进行判断,得到最终的结果,即关于图像的计算机语义描述。更多还原

【Abstract】 People’s apperceive and comprehension is subjective when they see pictures.Image understanding is a subject about interpreting image using computers by imitating the biological systems of human beings.It is important for research of facial animation that we extract the emotion embodied in pictures based on image understanding.We hope that computer can describe a picture in a semantic way by its own comprehension and inspire relative emotions.After this,we can use this result to drive a human facial model.In this paper,we deal with pictures of background especial pictures of weather.First a picture was segmented into two independent parts by color clustering.Then corresponding color characteristics were inputted into a educated Neural Network.At last we get a final result that is a computer semantic description about the picture after a judgement.Key words:Double glow Artificial neural network更多还原
