WebFeb 21, 2024 · The lossless compression scheme reaches a compression ratio of nearly 5%, which means that the point cloud is compressed to 5% of its original size without any distance distortion. Compared with other methods, the proposed compression algorithm also shows better performance. WebJun 1, 2024 · MPPCA needs to known the number and dimensions of subspaces in advance. Agglomerative Lossy Compression (ALC) seeks for the minimization of the overall coding length of the segmented data [ 5 ]. The agglomerative procedure in ALC still need to be proved theoretically.

A Novel Point Cloud Compression Algorithm Based On Clustering

WebWe show that such a mixture distribution can be effectively segmented by a simple agglomerative clustering algorithm derived from a lossy data compression approach. Using simple fixed-size Gaussian windows as texture features, the algorithm segments an image by minimizing the overall coding length of all the feature vectors. WebMar 18, 2009 · The goodness of clustering depends on the within-cluster errors, the between-clusters interaction, and a tuning parameter applied by TSCC.
