The aim of this study was to assess the reliability of a smartphone-based application developed for photographic-based goniometry, DrGoniometer (DrG), by comparing its measurement of the knee joint angle with that made by a universal goniometer (UG). Joint goniometry is a common mode of clinical assessment used in many disciplines, in particular in rehabilitation. One validated method is photog...

In this paper , we describe a relational modeling technique which categorizes three-dimensional objects at a gross level. These models may then be used to classify and recognize two dimensional views of the object, in a scene analysis system.

Imperative visual data frequently vanishes when color applications are seen by partially color blind users. A new method for adaptive interface for accommodating color blind users is presented. The method presented here has two sections: 1) test client perceivability by utilizing Ishihara plates. 2) change the interface color scheme to accommodate color blind users if necessary. We demonstrate ...

Speckle reduction techniques are applied to SAR imagery to produce images that are almost photographic in appearance ("quasi-photographic imagery"). A road tracking system designed for use with photographic imagery has been used to process this data. The road networks extracted from the quasi-photographic imagery are compared with those produced from optical imagery. It was found that the perfo...

Abs t rac t . In this paper, a new approach for retrieval from semistructured photographic collections is described. We have developed a retrieval model based on the Dempster-Shafer theory of evidence combination. Basic concepts of the Dempster-Shafer theory are explained and the suitability of this theory for information retrieval is explored. A retrieval model for a semi-structured photograph...

By applying the principle that all stellar image profiles should be identical apart from a scale change, we can derive a relative calibration for a photographic plate without use of calibration spots or other indirect means.

A simple dark-field photographic technique was developed which enables laboratory personnel with minimal photographic training to easily record antigen-antibody patterns on immunodiffusion plates.
