FFT and Convolution Performance in Image Filtering on GPU
O. Fialka,Martin Čadík +1 more
TL;DR: Conditions under which the FFT gives better performance than the corresponding convolution are identified and the different kernel sizes and issues of application of multiple filters on one image are assessed.
Proceedings ArticleDOI
An efficient perception-based adaptive color to gray transformation
TL;DR: A new color to grayscale transformation is presented, based on the experimental background of the Coloroid system observations, and a new simple, yet very efficient method is introduced to solve the inconsistency of the field.
Proceedings ArticleDOI
Automatic photo-to-terrain alignment for the annotation of mountain pictures
TL;DR: A novel automatic technique is proposed to avoid the burden of manual registration of a given photograph with a 3D geo-referenced terrain model, able to automatically derive the pose of the camera relative to the geometric terrain model.
Proceedings ArticleDOI
Video quality assessment for computer graphics applications
TL;DR: This work presents a full-reference video quality metric geared specifically towards the requirements of Computer Graphics applications as a faster computational alternative to subjective evaluation.
Journal ArticleDOI
Ink-and-ray: Bas-relief meshes for adding global illumination effects to hand-drawn characters
Daniel Sýkora,Ladislav Kavan,Martin Čadík,Ondřej Jamriška,Alec Jacobson,Brian Whited,Maryann Simmons,Olga Sorkine-Hornung +7 more
TL;DR: A new approach for generating global illumination renderings of hand-drawn characters using only a small set of simple annotations that exploits the concept of bas-relief sculptures, and forms an optimization process that automatically constructs approximate geometry sufficient to evoke the impression of a consistent 3D shape.
