Abstract
S tehniko urejanja slikovnih pik sliko obdelamo, jo popačimo in tako ustvarimo umetniško delo. Na prvi pogled je postopek nepredvidljiv, prisotnih pa je mnogo pravil, zaradi katerih se poveča zahtevnost tehnike in s tem čas obdelave. Da bi le tega zmanjšali, smo obdelavo vzporedili in jo razvili za izvajanje na grafičnem pospeševalniku. Tako smo izkoristili večino prednosti, ki nam jih le ta nudi, spoprijeti pa smo se morali tudi z omejitvami in posebnostmi. S testiranjem na različnih slikah smo obdelavo še bolj prilagodili in pospešili. Rezultati testiranja obdelave slike na naši strojni opremi so nam pokazali, da je čas obdelave z upoštevanjem standardnega odklona še vedno pod sprejemljivimi mejami za izvajanje obdelave v realnem času. Razvili in pripravili smo tudi cevovod, ki obdela videoposnetke, in v realnem času prikazuje obdelane slike.

Title:Pixel sorting on the GPU
Abstract:
We process and distort images with the pixel sorting tehnique and create art. The process is unpredictable at first glance, but there are many rules present which increase the complexity of the tehnique and with that the processing time. We parallelized the process and developed it to run on the GPU to reduce time. With that we utilized most of its advantages, but we also had to tackle its disadvantages and specialties. We further customized and accelerated the process by testing it on different images. Testing the process on our hardware shows, that the processing time, including standard deviation, is still under our acceptable upper limit, which allows for execution in real time. We also developed and prepared a pipeline, which processes videos and simultaneously displays the newly processed images.

Keywords:pixel sorting, parallel processing, computer graphics
