This pilot study evaluated the feasibility of the InsectEye image-analysis application for detecting visually identifiable respiratory motion in selected infrared nighttime video segments. An initial parameter optimization was performed using 13 one-minute video segments from nine dogs. The selected analysis conditions were subsequently evaluated in Experiment 1 using five 5 min video recordings from four dogs. Experiment 2 further assessed respiratory rate estimation using the same validation dataset. InsectEye-detected events were compared with visually confirmed respiratory motion using time-synchronized review. Two criteria were assessed: Both-only, requiring detection of both inspiratory- and expiratory-related motion, and Both+Either, accepting detection of either or both phases. Detection performance improved when the threshold was reduced from 10 to 8, particularly with the 256 \u00d7 120 mesh. The 256-120_15_8 condition yielded the highest mean detection rate (87.93 \u00b1 1.87%), fewer false-negative events, and shorter continuous non-detection duration, although false-positive detections increased. The Both+Either criterion performed better than the Both-only criterion. These findings support the feasibility of camera-based respiratory motion detection under selected favorable conditions, but larger studies using physiological respiratory reference methods are required before clinical monitoring or alerting applications can be established.<\/jats:p>","DOI":"10.3390\/vetsci13080781","type":"journal-article","created":{"date-parts":[[2026,8,4]],"date-time":"2026-08-04T12:32:43Z","timestamp":1785846763000},"page":"781","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Feasibility of Remote Camera-Based Respiratory Motion Detection in Hospitalized Dogs Using the InsectEye Image-Analysis Application: A Pilot Study"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-8423-8186","authenticated-orcid":false,"given":"Akihiro","family":"Ohnishi","sequence":"first","affiliation":[{"name":"Department of Veterinary Science, Okayama University of Science, 1-3 Ikoinooka, Imabari 794-8555, Ehime, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mio","family":"Takeuchi","sequence":"additional","affiliation":[{"name":"Department of Veterinary Science, Okayama University of Science, 1-3 Ikoinooka, Imabari 794-8555, Ehime, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryo","family":"Sakaguchi","sequence":"additional","affiliation":[{"name":"Department of Veterinary Science, Okayama University of Science, 1-3 Ikoinooka, Imabari 794-8555, Ehime, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Runa","family":"Iwata","sequence":"additional","affiliation":[{"name":"Department of Veterinary Science, Okayama University of Science, 1-3 Ikoinooka, Imabari 794-8555, Ehime, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Taketoshi","family":"Asanuma","sequence":"additional","affiliation":[{"name":"Department of Veterinary Science, Okayama University of Science, 1-3 Ikoinooka, Imabari 794-8555, Ehime, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshiki","family":"Itoh","sequence":"additional","affiliation":[{"name":"Chushikoku Animal Eye Clinic, 3-9-3 Imazu-cho, Fukuyama 729-0111, Hiroshima, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"59","DOI":"10.5326\/JAAHA-MS-7055","article-title":"2020 AAHA Anesthesia and Monitoring Guidelines for Dogs and Cats*","volume":"56","author":"Grubb","year":"2020","journal-title":"J.
