Abstract: The present disclosure relates to classifying and/or selecting images based on image segmentation. A classification system for classifying images includes one or more processors and at least one memory storing machine executable instructions. When the instructions are executed by the one or more processors, they cause the classification system to: access image segmentation scores for pixels of an image, and classify the entire image based on the image segmentation scores for the pixels of the image. The image segmentation scores for the pixels of the image are provided by an image segmentation system based on the image, and each of the image segmentation scores correspond to at least one pixel of the pixels of the image.

On user input, additional images corresponding to a currently displayed image may be displayed, where the additional images are automatically selected according to a second selection method. The second selection method may be based on a relation between images of the stream of in-vivo images and the currently displayed image.

Abstract: Methods for capturing and transmitting images by an in-vivo device comprise operating a pixel array in a superpixel readout mode to capture probe image, for example, according to a time interval. Concurrently to capturing of each probe image, the probe image is evaluated alone or in conjunction with other probe image(s), and if it is determined that no event of interest is detected by the last probe image, or by the last few probe images, the pixel array is operated in the superpixel readout mode and a subsequent probe image is captured. However, if it is determined that the last probe image, or the last few probe images, detected an event of interest, the pixel array is operated in a single pixel readout mode and a single normal image, or a series of normal image, is captured and transmitted, for example, to an external receiver.

Abstract: A visualization system may include a radiographic imaging apparatus for obtaining radioscopic images of a bodily organ with one or more radio discernible sensors introduced into the organ in order to sense physiological parameter(s) related to the physiological activity of the imaged organ. The sensors may be pressure sensors, temperature sensors, etc. The visualization system may also include a computing device for identifying the organ and the relative locations of the sensors in each radioscopic image, and it may generate a displayable representation symbol that may represent the sensors and the sensors' output values. Display attributes that depend on the sensors' locations and output values may define the location of the representation symbol. Acquiring a radioscopic image of the bodily organ and reading the sensors' outputs may be performed simultaneously in order to facilitate spatiotemporal synchronization between display of the image of the organ and display of the representation symbol.
