Bioystadegau a Gwyddor Data: Astudiaeth Profedigaeth COVID

Nod yr astudiaeth genedlaethol hon yw ymchwilio i brofiadau'r galar, anghenion cymorth a'r defnydd o gymorth profedigaeth gan bobl mewn profedigaeth yn ystod y pandemig yn y DU, a'r addasiadau, yr heriau a'r arloesedd sy'n gysylltiedig â darparu cymorth profedigaeth. Mae'n cael ei gynnal gan dîm o ymchwilwyr ym Mhrifysgol Caerdydd a Phrifysgol Bryste, gyda chyllid gan UKRI drwy'r Cyngor Ymchwil Economaidd a Chymdeithasol.

Prosesu Delweddau ac AI: Set ddata ARIA

Dadansoddiad Delwedd Retinol Awtomataidd (ARIA)

Mae'r set ddata ARIA yn gasgliad o ddelweddau retinol a gasglwyd fel rhan o'r prosiect Dadansoddi Delweddau Retinol Awtomataidd (ARIA) yn Uned Llygaid Sant Paul, Lerpwl, y DU (2004-2006) gen i a fy nhîm o ffotograffwyr. Pynciau oedd oedolion gwryw a benywod mewn tri grŵp eang: iach (grŵp rheoli), dirywiad macwlaidd sy'n gysylltiedig ag oedran (AMD), a diabetig. (Ar gael yn ôl y galw.)

Prosesu Delweddau ac AI: Delweddu Arwyneb 3D a Modelu Siâp

Aml-lefel aml-amrywiad cod atchweliad lluosog (ee, mPLSR) i fodelu (yn MATLAB) sut mae'r effeithiau cystadleuol o ryw, oedran, genynnau, BMI, amgylchedd, ac ati yn effeithio ar siâp yr wyneb ac i ymchwilio i ddeinameg wyneb. Defnyddiwyd yr ymchwil hon i archwilio newidiadau i'r wyneb mewn plant ysgol rhwng 11 a 18 oed. Dangosodd hefyd fod saith cam i wên!

Cipio delwedd 3D (dotiau gwyn) trwy gamera 3DMD. Model (dotiau glas a llinellau) trwy god PCA swyddogaethol aml-lefel a ddatblygwyd gan DJJF. Cefnogwyd y gwaith hwn gan gyllid teithio gan *Gymdeithas Fathemategol Llundain (LMS)* a *Rhaglen Gyfnewid Ryngwladol "Taith."*

Prosesu delweddau ac AI: Olrhain Llygaid a Dylunio Dail Gwybodaeth i Gleifion

Mewn astudiaeth a gynhaliwyd gennym ym Mhrifysgol Caerdydd, roedd olrhain llygaid yn cefnogi sylwadau testun rhydd a oedd yn dangos pwysigrwydd defnyddio delweddau i gyfleu gwybodaeth gymhleth. Roedd amseroedd gosod ar gwestiynau penodol yn uwch ar gyfer y pynciau hynny a atebwyd yn gywir yn y cwis, er nad oedd yr effaith hon yn arwyddocaol ar y cyfan (P > 0.05).

Delwedd trwy Tobii Pro Nano. Cefnogwyd yr ymchwil hon gan Grant Arloesi gan y *Sefydliad Ffiseg a Pheirianneg mewn Meddygaeth (IPEM).*
