A computer-assisted experiment to study the influence of the point spread function in the image formation process [PDF]

European Journal of Physics, 2018
Abstract We present a new open experimental setup assisted with LabView to be used to teach the concept of the point spread function (PSF). The PSF describes the response of an image-forming system to a point object. The PSF concept is of fundamental importance in optics since the output of an image-forming system can be simulated as ...

Multitraining support vector machine for image retrieval

, 2006
Relevance feedback (RF) schemes based on support vector machines (SVMs) have been widely used in content-based image retrieval (CBIR). However, the performance of SVM-based RF approaches is often poor when the number of labeled feedback samples is small.
