Given panoramic video taken along a self-intersecting path, we present a method for detecting the intersection points. This allows “virtual tours” to be synthesized by splicing the panoramic video at the intersection points. Spatial intersections are detected by finding the bestmatching panoramic images from a number of nearby candidates. Each panoramic image is segmented into horizontal strips...

In this paper, we propose an image rectification method to generate panoramic views from stereoscopic images. Due to different intrinsic and extrinsic characteristics of stereoscopic cameras, there are some mismatches in the vertical direction of the stereo images and they become major obstacles to make a panoramic image. Therefore, we need to reduce mismatches to generate more natural panorami...

AIM To compare digital panoramic images acquired for the presurgical assessment of third molars captured with a storage phosphor-based system with conventional film panoramic radiographs. METHODS AND MATERIALS A total of 51 pairs of digital and conventional panoramic images, made simultaneously, were included in this study. The images were evaluated for diagnostic quality prior to third molar...

OBJECTIVE To compare the nicotine content of 12 unfiltered brands of bidi cigarettes (hand rolled cigarettes imported from India) with 8 popular brands of filtered and unfiltered US and conventional cigarettes from India. MAIN OUTCOME MEASURES Identical laboratory procedures were used to determine nicotine content (in duplicate) and physical characteristics. RESULTS The nicotine concentrati...

The panorama-based annotation method described in this paper uses a panoramic image as the source of information about the positions of the annotations. It nds image alignment parameters between an input frame and the panoramic image and then maps the positions of annotations from the panoramic image to the input frame and displays the input frame overlaid with those annotations. Camera movemen...

AIMS This study used dried human mandibles and aimed to assess the effect of different horizontal condylar angle and the effect of different beam angles from three different units in the depiction of medial, central and lateral parts of the condyle on panoramic and lateral temporomandibular joint (TMJ) panoramic images. METHODS Standard panoramic and lateral TMJ panoramic images of four dried...

Traffic filters block clients from communicating with certain Internet destinations. To prevent clients from evading the filtering policies, traffic filters may also block access to well-known anonymizing proxies. In response, researchers have designed more sophisticated solutions techniques that rely on implicit proxies lying along the path to unfiltered destinations. An implicit proxy transpa...

What perceptual information do artists use to accurately render what they see? To answer this question, we investigated the utility of low, middle, and high spatial frequency bands for drawing. Untrained artists drew portraits from four spatial frequency bands (unfiltered, low, middle, and high). Raters judged the accuracy of those drawings compared to images of either the same or an unfiltered...

We wanted to determine whether the 2- to 4-fold increases in reading speed found for patients with age-related macular degeneration (ARMD) when reading filtered text, presented one word at a time in the middle of the display would also be found when filtered text was scrolled across the screen. Reading speeds for filtered text that compensates for an observer's reduced contrast sensitivity func...

We introduce a new class of panoramic images, called polycentric panoramic images, which is a generalization from more specific classes such as single-center, multiple-center, or concentric panoramic images. This paper focuses on the derivation of an epipolar curve equation for polycentric panoramic images. The epipolar curve equation derived provides a unified approach for the epipolar geometr...
