The technique has been experimentally evaluated and compared with traditional approaches to edge detection (Canny and Difference of Gaussians, or DoG) and with a more recent variant, specifically designed for stylization purposes (Flow Difference of Gaussians, or FDoG). An objective evaluation showed, after an ANOVA analysis and a Tukey t-test, that the proposed approach was equivalent to the FDoG technique and superior to the DoG. A\u00a0subjective experiment involving the opinion of human observers proved to be complementary to the objective analysis.<\/jats:p>","DOI":"10.1007\/s13173-012-0061-y","type":"journal-article","created":{"date-parts":[[2012,2,28]],"date-time":"2012-02-28T14:25:21Z","timestamp":1330439121000},"page":"237-250","update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Non-photorealistic neural sketching"],"prefix":"10.1007","volume":"18","author":[{"given":"Francisco de Assis Pereira Vasconce","family":"de Arruda","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jos\u00e9 Eust\u00e1quio Rangel","family":"de Queiroz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Herman Martins","family":"Gomes","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2012,2,29]]},"reference":[{"key":"61_CR1","first-page":"520","volume-title":"Proc IEEE SITIS 2007","author":"FA Arruda","year":"2007","unstructured":"Arruda FA, Porto VA, Gomes HM, de Queiroz JER, Moroney N (2007) Facial sketching based on sub-image illumination removal and multiscale edge filtering.
