  • Publication number: 20240079138
    Abstract: Systems and methods relate to predicting disease progression by processing digital pathology images using neural networks. A digital pathology image that depicts a specimen stained with one or more stains is accessed. The specimen may have been collected from a subject. A set of patches are defined for the digital pathology image. Each patch of the set of patches depicts a portion of the digital pathology image. For each patch of the set of patches and using an attention-score neural network, an attention score is generated. The attention-score neural network may have been trained using a loss function that penalized attention-score variability across patches in training digital pathology images labeled to indicate no or low subsequent disease progression. Using a result-prediction neural network and the attention scores, a result is generated that represents a prediction of whether or an extent to which a disease of the subject will progress.

  • Patent number: 11900694
    Abstract: A parking assist system for a vehicle includes an environment information obtainer, a storage, a parked vehicle detector, a space determiner, and a parking possibility determiner. The storage stores a reference parking width to be used for parking the vehicle. The parked vehicle detector detects a parked vehicle. The space determiner compares a width of a space next to the parked vehicle with the reference parking width and determines whether the width of the space is greater than or equal to the reference parking width. If the width of the space is found to be greater than or equal to the reference parking width, the parking possibility determiner determines whether a target object is detected at a back side of the space. If the target object is not detected, the parking possibility determiner determines that parking in the space is prohibited.

  • Patent number: 11875542
    Abstract: A parking assist system for a vehicle includes an environment information obtainer, a sufficient parking space setter, a parked-vehicle inter-space calculator, a parking capable space setter, and a parking assister. The environment information obtainer obtains environment information around the vehicle. The sufficient parking space setter sets a sufficient parking space for the vehicle by including a parking allowance width on each of left and right sides of the vehicle. The parked-vehicle inter-space calculator calculates a space between parked vehicles, based on the obtained environment information. The parking capable space setter compares the space between the parked vehicles with the sufficient parking space and, when determining the space between the parked vehicles is greater than or equal to the sufficient parking space, sets the space between the parked vehicles to be a parking capable space. The parking assister guides the vehicle to the parking capable space.

  • Patent number: 11144774
    Abstract: A system and a method for unveiling poorly visible or lightly colored nuclei in an input image are disclosed. An input image is fed to a color deconvolution module for deconvolution into two color channels that are processed separately before being combined. The input image is deconvolved into two separate images: a stain image and a counter stain image. A complement of the stain image is generated in order to clearly reflect the locations of the poorly visible or light-colored nuclei. The complement image and the counter stain image are optionally normalized and then combined and segmented, to generate an output image with clearly defined nuclei. Alternatively, the complement of the stain image and the counter stain image can optionally be normalized, and then segmented prior to being combined to generate the output image.
