PCs can be also used to generate alternative<br>representation of 3D visual content, like 3D meshes and emerging Gaussian splatting.<br>This talk will present the recent research and development for representation,<br>processing and evaluation of PCs, with humans and machines as ultimate users,<br>respectively. Related important topics include various filtering, simplification,<br>compression, registration, shape\/mesh construction, saliency\/quality evaluation, and<br>image-based localization. Possible future research directions will be highlighted and<br>discussed as well.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/cv.inf.elte.hu\/wp-content\/uploads\/2025\/05\/LinWeisiTalk-1024x768.jpg\" alt=\"\" class=\"wp-image-1047\" srcset=\"https:\/\/cv.inf.elte.hu\/wp-content\/uploads\/2025\/05\/LinWeisiTalk-1024x768.jpg 1024w, https:\/\/cv.inf.elte.hu\/wp-content\/uploads\/2025\/05\/LinWeisiTalk-300x225.jpg 300w, https:\/\/cv.inf.elte.hu\/wp-content\/uploads\/2025\/05\/LinWeisiTalk-768x576.jpg 768w, https:\/\/cv.inf.elte.hu\/wp-content\/uploads\/2025\/05\/LinWeisiTalk-1536x1152.jpg 1536w, https:\/\/cv.inf.elte.hu\/wp-content\/uploads\/2025\/05\/LinWeisiTalk.jpg 1920w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>On 13 May, Professor Weisi Lin from Nanyang Technological University, Singapore, visited our research group.
