Abstract: A method executed by a system for selecting images from a plurality of image groups originating from a plurality of imagers of an in-vivo device includes calculating, or otherwise associating, a general score (GS) for images of each image group, to indicate the probability that each image includes at least one pathology, dividing each image group into image subgroups, identifying a set Set(i) of maximum general scores (MGSs), a MGS for each image subgroup of each image group; and selecting images for processing by identifying a MGS|max in each set S(i) of MGSs; identifying the greatest MGS|max and selecting the image related to the greatest MGS|max. The method further includes modifying the set Set(i) of MGSs related to the selected image, and repeating the steps described above until a predetermined criterion selected from a group consisting of a number N of images and a score threshold is met.

Abstract: A system and method for identifying an in-vivo image frame with one or more polyps. Center points of candidate imaged structures may be determined, each center point defining a respective circle. Polyp edge scores may be computed for a plurality of points around each center point, each polyp edge score measuring the coincidence of a respective candidate imaged structure and its respective circle. For each center point, a plurality of edge points of the respective candidate imaged structure may be detected based on the polyp edge score and a candidate imaged structure may be identified based on the detected edge points. For each candidate imaged structure, a candidate polyp may be identified for which extrapolating the detected edge points forms an edge in a shape approximating an ellipse. Image frames with candidate polyps contributing to an above threshold overall image score are determined and marked to include a polyp.

Abstract translation: 一种用于用一个或多个息肉识别体内图像帧的系统和方法。 可以确定候选成像结构的中心点，每个中心点限定相应的圆。 可以针对每个中心点周围的多个点计算多边缘分数，每个息肉边缘分数测量相应候选成像结构及其相应圆的重合。 对于每个中心点，可以基于息肉边缘评分来检测相应候选成像结构的多个边缘点，并且可以基于检测到的边缘点来识别候选成像结构。 对于每个候选成像结构，可以识别候选息肉，其外推所检测的边缘点形成近似于椭圆的形状的边缘。 确定有助于上述阈值总体图像得分的候选息肉的图像帧并标记为包括息肉。
