  • Patent number: 10293483
    Abstract: An apparatus and methods for training and/or operating a robotic device to follow a trajectory. A robotic vehicle may utilize a camera and stores the sequence of images of a visual scene seen when following a trajectory during training in an ordered buffer. Motor commands associated with a given image may be stored. During autonomous operation, an acquired image may be compared with one or more images from the training buffer in order to determine the most likely match. An evaluation may be performed in order to determine if the image may correspond to a shifted (e.g., left/right) version of a stored image as previously observed. If the new image is shifted left, right turn command may be issued. If the new image is shifted right then left turn command may be issued.

  • Patent number: 10277960
    Abstract: A computer-implemented method and system for seeding video programs with episodic interactive items improve computer performance by averting tracking loss. The system includes a scene map table that maintains a scene record for every scene in the video. The scene record contains boundary information for the scene and linking information to companion scenes that are visually similar. When a developer tags an episodic item in the video for interactivity, the scene record for the scene where the item is tagged is accessed in the scene map table. The boundary information from this scene record is used to track the item across the scene without tracking loss and the linking information from this scene record is used to access scene records for companion scenes, allowing the item to be tracked across the companion scenes without tracking loss.

  • Patent number: 9858500
    Abstract: The subject technology provides embodiments for performing fast corner detection in a given image for augmented reality applications. Embodiments disclose a high-speed test that examines intensities of pairs of pixels around a candidate center pixel. In one example, the examined pairs are comprised of pixels that are diametrically opposite ends of a circle formed with the candidate center pixel. Further, a pyramid of images including four rings of surrounding pixels is generated. An orientation of the pixels from the four rings are determined and a vector of discrete values of the pixels are provided. Next, a forest of trees are generated for the vector of discrete values corresponding to a descriptor for a first image. For a second image including a set of descriptors, approximate nearest neighbors are determined from the forest of tree representing closest matching descriptors from the first image.

  • Patent number: 9836835
    Abstract: A technique is disclosed for helping prevent image quality of a three-dimensional image from becoming poor due to fluctuations in the rotation speed of an imaging core. For this purpose, if data is obtained from the imaging core by moving and rotating the imaging core, a cross-sectional image is generated at each movement position. Then, a direction where a guidewire is present in each of the cross-sectional images is detected. An angular difference between the direction of the detected guidewire and a preset direction is obtained so as to rotate each of the cross-sectional images in accordance with the angular difference. Then, the cross-sectional images which are previously rotated in this way are connected to one another, thereby generating the three-dimensional image.

  • Patent number: 9784587
    Abstract: A method includes applying a correlation rule defining a correlation relationship between a first and second object and determining, using a processor, whether a first motion vector of the first object is correlated at a threshold level of correlation with a second motion vector of the second object, the correlation relationship between the first and second objects identifying the threshold level of correlation between the first and second motion vectors. The method also includes, in response to determining that the first motion vector is not correlated at the threshold level with the second motion vector, determining a convergence point for the first and second objects in accordance with a policy. The method further includes transmitting instructions for arriving at the convergence point to the first and second objects.

  • Patent number: 9779497
    Abstract: Measuring the number of glomeruli in the entire, intact kidney using non-destructive techniques is of immense importance in studying several renal and systemic diseases. In particular, a recent Magnetic Resonance Imaging (MRI) technique, based on injection of a contrast agent, cationic ferritin, has been effective in identifying glomerular regions in the kidney. In various embodiments, a low-complexity, high accuracy method for obtaining the glomerular count from such kidney MRI images is described. This method employs a patch-based approach for identifying a low-dimensional embedding that enables the separation of glomeruli regions from the rest. By using only a few images marked by the expert for learning the model, the method provides an accurate estimate of the glomerular number for any kidney image obtained with the contrast agent. In addition, the implementation of our method shows that this method is near real-time, and can process about 5 images per second.

  • Patent number: 9754176
    Abstract: The present invention is directed to a method of extracting data from fields in an image of a document. In one implementation, a text representation of the image of the document is obtained. A graph for storing features of the text fragments in the text representation of the image of the document and their links is constructed. A cascade classification for computing the features of the text fragments in the text representation of the image of the document and their link is run. Hypotheses about the belonging of text fragments to the fields in the image of the document are generated. Combinations of the hypotheses are generated. A combination of the hypotheses is selected. And data from the fields in the image of the document is extracted based on the selected combination of the hypotheses.

    Abstract: First, images are captured with three exposure levels, and pixel levels of a low exposure image and an intermediate exposure image are amplified to be matched to those of a high exposure image. Next, a brightness combining ratio for each image is calculated based on the low exposure image that has been matched in brightness. Then, images having brightness combining ratios that are not 0% in a region of interest are selected, and only the selected images are used to generate a combined image in the region of interest, and the low exposure image is used as a substitute, for example, in a region other than the region of interest.
