Abstract: An approximate positions-of-people determination means determines, for each partial area, approximate positions of people on an image on the basis of information about the partial area. A states-of-people estimation means, in addition to predicting the current states of particles from the states of particles indicating past states of people and stored in a storage means, adds new particles and evaluates the likelihood of the states of predicted particles and the added particles on the basis of an observation model generated for the observed people to update the weights of the particles, performs particle re-sampling at a probability proportional to the weights of those particles, and outputs the states of the obtained particles as a flow of people.

Abstract: The present application relates generally to identifying regions of interest in images, including but not limited to whole slide image region of interest identification, prioritization, de-duplication, and normalization via interpretable rules, nuclear region counting, point set registration, and histogram specification color normalization.

Techniques directed to quality control estimation, granular classification, and coarse classification of regions of biomedical images are described herein. Using the described techniques, patches of images corresponding to regions of interest can be extracted and analyzed individually or in parallel to determine pixels correspond to features of interest and pixels that do not.

Abstract: Provided are automated (computerized) methods and systems for analyzing digitized pathology images in a variety of tissues potentially containing diseased or neoplastic cells. The method utilizes a coarse-to-fine analysis, in which an entire image is tiled and shape, color, and texture features are extracted in each tile, as primary features. A representative subset of tiles is determined within a cluster of similar tiles. A statistical analysis (e.g. principal component analysis) reduces the substantial number of “coarse” features, decreasing computational complexity of the classification algorithm. Afterwards, a fine stage provides a detailed analysis of a single representative tile from each group. A second statistical step uses a regression algorithm (e.g. elastic net classifier) to produce a diagnostic decision value for each representative tile. A weighted voting scheme aggregates the decision values from these tiles to obtain a diagnosis at the whole slide level.

Abstract: A free-form lens (for example a phase modulator, lens or deformable mirror) may be made to reproduce a light pattern specified by image data. Source regions on the free-form lens are mapped to target regions areas on an image. Areas of the source regions are adjusted to vary the amount of light delivered to each of the target regions. Adjustment of the source areas may be achieved using a L-BFGS optimization which preferably incorporates smoothness and curl regularizers. Embodiments apply parallel processing to obtain control values for a free form lens in real time or near real time. Apparatus may process image data and display an image by controlling a dynamically variable free form lens using the processed image data.

Abstract: Techniques for de-aliasing depth ambiguities included within infrared phase depth images are described herein. An illuminator emits reference light towards a target object. Some of this light is reflected back and detected. A phase image is generated based on phase differences between the reference light and the reflected light. The phase differences represent changes in depth within overlapping sinusoidal periods of the reference and reflected light. The phase image also includes ambiguities because multiple different depths within the phase image share the same phase difference value, even though these depths actually correspond to different real-world depths. The phase image is fed as input to a machine learning (“ML”) component, which is configured to de-alias the ambiguities by determining, for each pixel in the phase image, a corresponding de-aliasing interval. A depth map is generated based on the phase image and any de-aliasing intervals generated by the ML component.

Abstract: An apparatus for automatic target recognition with reinforcement learning is provided. The apparatus receives an image of a scene and performs an automatic target recognition on the image to detect objects in the image as candidate targets. The apparatus divides the candidate targets into subsets of candidate targets and performs a verification of the automatic target recognition to identify true targets in the image. In the verification, the apparatus solicits user input to manually identify some true targets in the image. The verification is performed according to a reinforcement learning process to minimize a total verification time.

Abstract: Systems and associated methods relate to classification of documents according to their spectral frequency signatures using a deep neural network (DNN) and other forms of spectral analysis. In an illustrative example, a DNN may be trained using a set of predetermined patterns. A trained DNN may, during runtime, receive documents as inputs, where each document has been converted into a spectral format according to a (2D) Fourier transform. Some exemplary methods may extract periodicity/frequency information from the documents based on the spectral signature of each document. A clustering algorithm may be used in clustering/classification of documents, as well as searching for documents similar to a target document(s). A variety of implementations may save significant time to users in organizing, searching, and identifying documents in the areas of mergers and acquisitions, litigation, e-discovery, due diligence, governance, and investigatory activities, for example.

Abstract: To precisely identify a state of an athlete who is present in a swimming pool, a processor used in a device for identifying a state of an athlete or a method for identifying a state of an athlete refers to a result of performing processing of detecting the athlete in a video image obtained by imaging the athlete who is present in the swimming pool and identifies an advancing direction of the athlete as a direction that is different from the previous advancing direction on the basis of a result of the detection of the athlete after the athlete is present in a region on the side of an end of the swimming pool. In this manner, it is possible to more accurately identify the advancing direction of the athlete and to thereby precisely identify the state of the athlete who is present in the swimming pool.

Abstract: Exemplary quantitative susceptibility mapping methods, systems and computer-accessible medium can be provided to generate images of tissue magnetism property from complex magnetic resonance imaging data using the Bayesian inference approach, which minimizes a cost function consisting of a data fidelity term and two regularization terms. The data fidelity term is constructed directly from the complex magnetic resonance imaging data. The first prior is constructed from matching structures or information content in known morphology. The second prior is constructed from a region having an approximately homogenous and known susceptibility value and a characteristic feature on anatomic images. The quantitative susceptibility map can be determined by minimizing the cost function. Thus, according to the exemplary embodiment, system, method and computer-accessible medium can be provided for determining magnetic susceptibility information associated with at least one structure.

Abstract: Systems and methods for counting objects in images based on each object's approximate location in the images. An image is passed to a segmentation module. The segmentation module segments the image into at least one object blob. Each object blob is an indication of a single object. The object blobs are counted by a counting module. In some embodiments, the segmentation module segments the image by classifying each image pixel and grouping nearby pixels of the same class together. In some embodiments, the segmentation module comprises a neural network that is trained to group pixels based on a set of training images. A plurality of the training images contain at least one point marker corresponding to a single training object. The segmentation module learns to group pixels into training object blobs that each contain a single point marker. Each training object blob is thus an indication of a single object.
