However, no image quality assurance systems exist for this purpose, despite image triage being considered the best practice approach. Hence, this study aimed at testing a semi-quantitative scoring method to assess image quality and investigated facial image resolution and lighting quality quantitatively in a context of forensic facial comparison. For this purpose, 400 facial comparison photographic and CCTV image pools developed from the Wits Face Database were used. These facial images were analysed in prior studies that investigated the validity of morphological analysis. A semi-quantitative image quality scoring system was adapted and tested on the above sample and compared across correct and incorrect matches obtained as part of previous studies using a logistic regression model. In addition, facial images were cropped to the closest pixel comprising the face, head and neck areas; then, a face-to-image pixel proportion was calculated as an estimator of resolution quality; and pixel exposure qualities were obtained to be compared to facial comparison outcomes. Ideal and high image quality scores were related to correctness of matches, while low-quality scores were related to incorrect matches. High pixel proportions were related to true matches and low exposure was related to false positives, while high exposure was related to false negatives. These results suggest that an easy method for image triage could be employed by scoring image quality. Quantitative measures should be investigated further for thresholding quality suitability for confidence of facial comparisons.<\/jats:p>","DOI":"10.1007\/s00414-024-03190-7","type":"journal-article","created":{"date-parts":[[2024,2,22]],"date-time":"2024-02-22T02:03:51Z","timestamp":1708567431000},"page":"1713-1726","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Prioritising quality: investigating the influence of image quality on forensic facial comparison"],"prefix":"10.1007","volume":"138","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6858-7598","authenticated-orcid":false,"given":"Nicholas","family":"Bacci","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8544-6049","authenticated-orcid":false,"given":"Nanette","family":"Briers","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0215-9723","authenticated-orcid":false,"given":"Maryna","family":"Steyn","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2024,2,22]]},"reference":[{"key":"3190_CR1","doi-asserted-by":"publisher","first-page":"743","DOI":"10.1016\/j.scijus.2021.09.003","volume":"61","author":"N Bacci","year":"2021","unstructured":"Bacci N, Steyn M, Briers N (2021) Performance of forensic facial comparison by morphological analysis across optimal and suboptimal CCTV settings.
