This　paper　proposes　an　algorithm　to　process　data　of　high-precision　sensor　array　with　data　compression.　To　eliminate　the　jitter　in　pressure　sensing,　the　Speeded-up　Robust　Features(SURF),　Fast　Approximate　Nearest　Neighbor　Search　Library(FLANN),　RANdom　SAmple　Consensus(RANSAC),　Gaussian　filter　and　motion　compensation　are　implemented.　Moreover,　data　compression　is　conducted　based　on　JPEG-LS　and　Run-length　coding.　As　a　result,　the　proposed　algorithm　achieves　the　jitter　eliminating　and　high　compression　ratio.　©　2020　IEEE.
