Given a PCA factorization of each cluster into subspaces and a maximal compression error, we show that the selection of those subspaces that provide the optimal lossy image compression is equivalent to the 0-1 Knapsack Problem. We present a theoretical and an experimental comparison between accurate and approximate algorithms for solving the 0-1 Knapsack problem in the case of lossy image compression. %G English %Z TC 8 %2 https://inria.hal.science/hal-01405649/document %2 https://inria.hal.science/hal-01405649/file/978-3-662-45237-0_52_Chapter.pdf %L hal-01405649 %U https://inria.hal.science/hal-01405649 %~ SHS %~ IFIP-LNCS %~ IFIP %~ IFIP-TC %~ IFIP-TC8 %~ IFIP-LNCS-8838 %~ IFIP-CISIM
