摘要:
A method and system for determining intestinal dysfunction condition are provided by classifying and analyzing image frames captured in-vivo. The method and system also relate to the detection of contractile activity in intestinal tracts, to automatic detection of video image frames taken in the gastrointestinal tract including contractile activity, and more particularly to measurement and analysis of contractile activity of the GI tract based on image intensity of in vivo image data.
摘要:
A device, system and method for automatic detection of contractile activity of a body lumen in an image frame is provided, wherein image frames during contractile activity are captured and/or image frames including contractile activity are automatically detected, such as through pattern recognition and/or feature extraction to trace image frames including contractions, e.g., with wrinkle patterns. A manual procedure of annotation of contractions, e.g. tonic contractions in capsule endoscopy, may consist of the visualization of the whole video by a specialist, and the labeling of the contraction frames. Embodiments of the present invention may be suitable for implementation in an in vivo imaging system.

A method for processing a sequence of ultrasound frames for display includes receiving a sequence of ultrasound frames; characterizing a morphology of regions within a plurality of the ultrasound frames; determining a frame profile for each of the plurality of ultrasound frames; detecting a plurality of key frames from the plurality of ultrasound frames using the frame profiles of the plurality of ultrasound frames; and displaying at least one of the key frames.

A method for generating an ultrasound image includes receiving a sequence of intravascular ultrasound (IVUS) data obtained as an IVUS imager moves through a body lumen; identifying at least one bifurcation of the body lumen from the sequence of IVUS data; determining a bifurcation angle between two branches of the body lumen; and displaying a longitudinal view of the body lumen using the IVUS data and incorporating the bifurcation angle to angularly align portions of the longitudinal view corresponding to the two portions of the body lumen.

A computer-implemented method for teaching math is disclosed. The method comprises displaying a number line graphic to indicate a relative order between numbers; generating a first problem comprising numbers at least some of which are indicated on the number line graphic; selectively providing guidance for solving the problem; and receiving a user's input as a solution to the first problem.
摘要:
A system and method for comparing captured sequences of in-vivo images with (e.g., template or model) sequences, for example, for computer-automated recognition of contractions. The size of the opening of an in-vivo lumen passageway represented in each frame in a subset of frames of an image stream captured in vivo may be measured. Frames in the subset of frames of the image stream having a local minimum size of the lumen passageway may be identified. The subset of frames may be divided into segments of sequential frames at frames having local maximum lumen sizes before and after the identified frame having a local minimum size of the lumen passageway to generate contraction sequences. A plurality of the contraction sequences may be compared to template sequences. A plurality of the contraction sequences may be displayed.
摘要:
A system and method for comparing captured sequences of in-vivo images with (e.g., template) sequences, for example, for computer-automated diagnosis. Captured in vivo images may be divided into a plurality of captured image sequences. For each of the plurality of captured sequences, the processor may assign a first and second set of scores to each frame in the captured sequence and align each frame in the captured sequence with one or more frames in the template sequence for which the comparisons therebetween generate the minimum scores in the first and second sets of scores. The processor may define a match between the template sequence and captured sequences having a combination of scores in the first and second sets of scores for the frames in the captured sets compared with the one or more aligned frames in the template sequence, which are below or above a threshold value.

A computer-implemented method for teaching math is disclosed. The method comprises generating a number; generating movable items corresponding to the number defining a number of place values for representing the number; graphically marking place value areas corresponding to the place values; allowing a user to move the movable items into the place value areas to represent the number in terms of its place values.
