Vision\nalgorithms based on them are still not common. As a consequence, there are few\nHardware Accelerators for them. In this work we present some experiments to\ncreate FPGA accelerators for a well-known vision algorithm using event-based\ncameras. We present a stereo matching algorithm to create a stream of disparity\nevents disparity map and implement several accelerators using the Intel FPGA\nOpenCL tool-chain. The results show that multiple designs can be easily tested\nand that a performance speedup of more than 8x can be achieved with simple code\ntransformations.","url_abs":"http://arxiv.org/abs/1903.03509v1","url_pdf":"http://arxiv.org/pdf/1903.03509v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"opencl-based-fpga-accelerator-for-disparity","repo_url":"https://github.com/davidcastells/DVSSimulator","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":0,"framework":"none","reach":null}],"tasks":[{"task_slug":"stereo-matching-1","task_name":"Stereo Matching"},{"task_slug":"stereo-matching","task_name":"Stereo Matching Hand"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"syntology_url":null,"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
