This paper studies the performance of various scale- invariant detectors in the context of feature matching. In particular, we propose an implementation of the Hessian-Laplace operator that we called scale-interpolated Hessian-Laplace. This research also proposes to use Haar descriptors which are derived from the Haar wavelet transform. It offers the(More)
Advancements in human computer interaction (HCI), and information and communication technology (ICT) resulted in developing of various assistive technologies especially for People with Disabilities (PWD). There are many assistive technologies and applications available these days. However, most of the available solutions focus on a particular type of(More)
In this study, we investigated the effect of viewpoint density and speed of motion on perceived smoothness of viewpoint transitions. The effect of viewpoint density was examined for two types of viewer motion: forward and lateral motion. In both cases, we found that perceived smoothness varies with viewpoint density. We also found the number of viewpoints(More)
