Description
  • Otázka obrazové kvalita obrazové nebo video informace je v bezpeenostních obrazových systémech zásadní. Ná1 elánek se zabývá toemi ruznými otázkami – aposteriorním vylep1ováním obrazu, objektivním hodnocením kvality a odstraoováním 1umu. V první eásti jsme testovali a hodnotili vliv hranových operátoru. Tyto mají dva protichudné úeinky – zostoení hran a zvý1ení úrovni 1umu. Druhá eást shrnuje problematiku pou3ití umilých neuronových sítí ANN v procesu objektivního hodnocení kvality obrazu. Nový poístup je zalo3en na dvou pokroeilých metodách - vzájemné informace MI a analýzy hlavních slo3ek PCA. Toetí eást je vinována odstraoování 1umu pomocí DWT a prezentaci experimentálních výsledku.

  • The image quality of image or video information is a crucial issue in security imaging systems. Our paper deals with three different points – a posteriori image improvement, objective image quality assessment and noise removal. In the first part we have tested and evaluated the impact of edge-enhancing operators. Their performance is of two contradictory effects – edge sharpening and noise level increase. The second part summarizes the ANN application in the objective image quality evaluation procedure. The advanced approach is based upon two advanced methods – Mutual Information MI and Principal Component Analysis PCA. The third part is devoted to the DWT noise-removal technique and the experimental results are presented.
