This system improves robotic functionality by incorporating algorithms optimized for how computerized devices process visual information. Central to this paper\u2019s approach is an improved Fast Discrete Cosine Transform (FDCT) algorithm, customized for robotic systems, which enhances object and obstacle detection in machine vision. By prioritizing higher frequencies and eliminating less critical lower frequencies, the algorithm sharpens focus on essential details. Instead of adapting the data stream for human vision, the FDCT and quantization tables were adjusted to suit machine vision requirements, achieving a file size reduction to about one-third of the original while preserving highly relevant data for robotic processing. This innovative approach significantly improves robots\u2019 ability to navigate complex environments, perform tasks such as object recognition, motion detection, and obstacle avoidance with greater accuracy and efficiency.<\/jats:p>","DOI":"10.3390\/s26020518","type":"journal-article","created":{"date-parts":[[2026,1,13]],"date-time":"2026-01-13T10:13:51Z","timestamp":1768299231000},"page":"518","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Achieving Robotic Data Efficiency Through Machine-Centric FDCT Vision Processing"],"prefix":"10.3390","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4221-1549","authenticated-orcid":false,"given":"Yair","family":"Wiseman","sequence":"first","affiliation":[{"name":"Computer Science Department, Bar-Ilan University, Ramat-Gan 5290002, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Mahadik, S.C., Deulgaonkar, V.R., Bhosle, S.M., Dhamdhere, O.A., Taware, N.S., Darade, N.D., and Gadhave, G.J.
