1. 1. Shape depiction using Local Light Alignment : Evaluating the shape enhancement capabilities of the Local Light Alignment technique at multiple scales

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Edvard Ahlsén; [2023]
   Nyckelord :Shape depiction; Non-photorealistic rendering; Shading; Multiple scales; Formskildring; ickerealistisk rendering; skuggning; skalrymdsmetoder;

   Sammanfattning : Local Light Alignment is a new shading based technique in the field of shape depiction, a field which concerns itself with techniques to represent and enhance the three-dimensional (3D) shape of objects in two-dimensional (2D) visual media. The main idea of Local Light Alignment is to locally adjust the incoming direction of light to create contrast in a way that enhances the perception of shape and surface detail. LÄS MER

3. 2. Scale-Space Methods as a Means of Fingerprint Image Enhancement

   Författare :Karl Larsson; [2004]
   Nyckelord :Datorteknik; fingerprint; template aging; correlation; image enhancement; scale-space; Gaussian scale-space; linear scale-space; nonlinear isotropic scale-space; nonlinear anisotropic scale-space; diffusion; scalar driven diffusion; scalar dependent diffusion; tensor driven diffusion; tensor dependent diffusion; Datorteknik;

   Sammanfattning : The usage of automatic fingerprint identification systems as a means of identification and/or verification have increased substantially during the last couple of years. It is well known that small deviations may occur within a fingerprint over time, a problem referred to as template ageing. LÄS MER
