Title: Filippo Passaggio: Innovator in Image Compression Technologies
Introduction
Filippo Passaggio is a notable inventor based in Genoa, Italy. He has made significant contributions to the field of image compression, holding a total of 3 patents. His work focuses on developing efficient coding methods for binary matrices, particularly in applications involving sparse binary matrices.
Latest Patents
One of his latest patents is titled "Lossless image compression with tree coding." This invention involves a method and device for coding binary matrices, where a matrix is gradually partitioned into sub-matrices. During this partitioning, the number of binary ones is counted for each resulting sub-matrix. If a sub-matrix does not consist of mixed symbols, no further partitioning is required. The counted number of binary ones is then coded and transmitted, providing an efficient coding method for sparse binary matrices such as bi-level images or bit maps.
Another significant patent is "Non-reversible differential predictive compression using lossy or lossless tables." This invention utilizes the correlation between successive digital numbers to create a new stream with low correlation, allowing for more efficient coding from a compression perspective. The numbers are coded based on the difference between a predicted number and the actual number, with the flexibility to adapt to varying bandwidth conditions during data transmission.
