PURPOSE With the advancement of ultrasound-guidance for peripheral nerve blocks, still pictures from representative ultrasonograms are increasingly used for clinical procedure documentation of the procedure and for educational purposes in textbook materials. However, little is actually known about the clinical and educational usefulness of these still pictures, in particular how well nerve stru...

In 1996, the JPEG committee began to investigate possibilities for a new still image compression standard to serve current and future applications. This initiative, which was named JPEG2000, has resulted in a comprehensive standard (ISO 15444 | ITU-T Recommendation T.800) that is being issued in six parts. Part 1, in the same vein as the JPEG baseline system, is aimed at minimal complexity and ...

Most of the video information retrieval systems today rely on some set of computationally extracted video and/or audio features, which may be complemented with manually created annotation that is usually either arduous to create or insufficient for capturing the content. This thesis looks at the specific domain of motion pictures to identify the computational features relevant to films and, mor...

Most everyday scenes have a far greater dynamic range than can be recorded on a photographic lm or electronic imaging apparatus (whether it be a digital still camera, video, etc.). However, a set of pictures, that are identical except for their exposure, collectively show us much more dynamic range than any single picture. The dark pictures show us highlight details of the scene that would be w...

The effects of differences in study processing on free recall of picture names and on generalization in picture identification were investigated. Experience with degraded pictures produced poorer subsequent free recall of picture names than did naming intact pictures. For the test of picture identification, pictures that were identical to a studied picture, pictures that shared a name with a st...

Three experiments investigated the effects of two variables -selective attention during encoding and delay between study and test- on implicit (picture fragment completion and object naming) and explicit (free recall and recognition) memory tests. Experiments 1 and 2 consistently indicated that (a) at all delays (immediate to 1 month), picture-fragment identification threshold was lower for the...

The present study investigates the central concerns of the use of visuals within the four EFL textbooks taught at Iranian high schools which have been prescribed by the Ministry of Education. To do this, the four EFL textbooks were evaluated and analyzed. Descriptive statistics were used to analyze data quantitatively. The analysis indicated that over the four textbooks, 95.71 percent of all vi...
