  • Patent number: 8983206
    Abstract: A visual quality assessment method and system are based on deriving a quality metric by comparing sub-band approximations of a distorted image and an undistorted version of the same image, providing a good compromise between computational complexity and accuracy. The sub-band approximations are derived from Discrete Wavelet (Haar) transforms of small image blocks of each image. Due to inherent symmetries, the wavelet transform is “blind” to certain types of distortions. But the accuracy of the method is enhanced, and the blindness of the transform is overcome, by computing quality metrics for the distorted image as well as computing quality metrics for a shifted version of the distorted image and combining the results.

    Abstract: Systems and methods for relating images to each other by determining transform functions between the images and the three-dimensional world coordinate system of the object depicted in the image, without using image acquisition metadata are disclosed. Points of interest are independently selected on each image. An initial transform function is applied to transform the points in the plane of one image to the plane of the other image. A Gaussian Mixture Model is then iteratively applied to the points to determine a best match, which then provides adjustments to the argument values of the transform function which is again applied to the points of interest on each image. This process repeats until the argument values converge to provide the resulting transform function. The resulting function can then be used to identify objects in the images in three dimensional space.

  • Patent number: 8638987
    Abstract: An image-based hand detection apparatus includes a hand image detection unit for detecting a hand image corresponding to a shape of a hand clenched to form a fist from an image input. A feature point extraction unit extracts feature points from an area, having lower brightness than a reference value, in the detected hand image. An image rotation unit compares the feature points of the detected hand image with feature points of hand images stored in a hand image storage unit, and rotates the detected hand image or the stored hand images. A matching unit compares the detected hand image with the stored hand images and generates a result of the comparison. If at least one of the stored hand images is matched with the detected hand image, a hand shape recognition unit selects the at least one of the stored hand images as a matching hand image.

  • Publication number: 20130272571
    Abstract: An imaging system captures images of a human submental profile in a dimension controlled environment and utilizes image analysis algorithms for detecting submental changes. Instead of implementing a strict posture control of a subject, the imaging system allows the subject to freely move his/her head in an up-and-down direction and a high speed camera captures this movement through a series of images at varying head-to-shoulder angles. The image analysis algorithms may accurately compare before and after images at similar head-to-shoulder angles to identify changes in a human submental profile using a series of measurements and checkpoints.

  • Patent number: 8559729
    Abstract: Systems and methods automatically generate a model of a form or other document and identify the form or other document. In one aspect, a system and method normalize an image of a document and identify the relative positions of vertical and horizontal lines in the normalized image. The relative positions of vertical and horizontal lines of the normalized image are the model of the document image. The model may be stored in a record, such as an array. The system and method compare the relative positions of vertical and horizontal lines of the model to the relative positions of vertical and horizontal lines of other models to identify a matching model.

  • Patent number: 8483488
    Abstract: A method and system for generating stabilized intravascular ultrasonic images are provided. The system includes a probe instrument, having an ultrasonic signal transmitter and a reflected ultrasonic signal receiver, the reflected signals containing information about a tubular environment, and a processor and post-processor, capable of converting inputted signals into one or more, preferably a series of, images. The method for stabilizing images involves the processor and post-processor input and output. The post-processor determines the environment center at each reflection position, detects the tubular environment edges, and aligns the image center with the environment center thereby limiting image drift and stabilizing the images. The processor may also filter images to improve image stabilization and remove motion interference and/or extract the environment's 3D shape. The method and device are of particular use in a vascular lumen, where image drift may occur due to heart beat or blood flow.
