教授詹姆斯·D·福莱特在佐治亚理工学院的计算机学院分享了关于计算机图形学的讲座，探讨了创建最逼真图像的必要性和目的，包括欺骗视觉和情感的变化。教授强调了图像真实感与效果之间的关系，并通过比较真实图片与合成图片来说明识别表面属性的重要性。此外，教授还提到了图形学在情绪治疗中的应用，以及在快速发展的技术背景下，如何通过‘少即是多’的原则来帮助用户识别和学习面部特征。
On October 9th, Professor James D. Foley, who is in the College of Computing at Georgia Tech, gave a lecture on ”A Computer Graphics Grand Challenge: How Real is Real Enough?”. Histopic was very attractive and I learned some knowledge of the computer graphics about realism. I feel honored to have the chance and my English has gradually improved.
There is no doubt that Computer Graphics become more and more popular. For present, it is tempting to create the very most realistic images using the latest and greatest techniques. Professor James D. Foley considered the problems and had a talk with us about whether it is necessary. His answer is “it depends”.
One of the purposes for which the graphics are being created is to fool the eye. He lists pairs of pictures and let us recognize which one is real. But to our surprise, wecan not get the right result because they looks same. He made a comparison between a real picture and a synthetics pictures and told us it hard to recognize but we can bring surface properties. If you are a experienced people,it is easy to choose the real pictures.
Another purpose is to fool the emotions. He showed some videos and images for us to distinguish the differences between the force smile and the emotion smile. ComputerGraphics can create images to simulate the action of face . Forced smile with twinkling looks more real in anime. Graphics can help create emotional changes in short term and in long term. Professor made emphasis on its benefits, which can help overcome various of fear by ”VR therapy”.
Moreover, helping the users is also important so that we can’t ignore it. Professor teaches us to recognize and learn faces. Sometimes, “less is more”. To our surprise, a sketch is better to recognize than a real photo. Other times, “more is more”. The more features you have, the more easily we indentify objects.
In conclusion, Professor categorize some of the purposes for which we create images. He is experienced and answered many questions seriously. I have a knowledge of the relationship between image realism and image effectiveness. I was surprised for the rapid development of graphics, and I will make more efforts to learn Computer Graphics well.
