Abstract: Images are analyzed using sub-sectional component evaluation in order to augment classifier usage. An image of an individual is obtained. The face of the individual is identified, and regions within the face are determined. The individual is evaluated to be within a sub-sectional component of a population based on a demographic or based on an activity. An evaluation of content of the face is performed based on the individual being within a sub-sectional component of a population. The sub-sectional component of a population is used for disambiguating among content types for the content of the face. A Bayesian framework that includes a conditional probability is used to perform the evaluation of the content of the face, and the evaluation is further based on a prior event that occurred.

In certain embodiments, the system further comprises a housing assembly and the first and second rotating magnetic field transmitter assemblies are positioned within the housing.

Abstract: Abnormalities of blood vessels associated with brains of individuals can be detected by analyzing images that include the brains of the individuals. Blood vessels included in the images can be identified and densities of blood vessels across hemispheres can be determined. Differences between densities of blood vessels in different hemispheres of the brains of the individuals can be used to determine a probability of an abnormality with respect to one or more blood vessels associated with the brains of the individuals. User interfaces can be generated indicating possible abnormalities associated with the brains of the individuals.

Abstract: A new and/or novel image analysis technique for quantitative assessment of motion-based testing for injury in a patient using universally available and affordable devices and techniques is provided and disclosed. A video of a test being performed can be processed to track the motion of markers and/or bodily landmarks in two or more dimensions to quantitatively describe motion, thereby removing the subjective aspects typically associated with motion-based testing. In an example, the pivot shift test is a commonly used test for evaluating rotational instability of the anterior cruciate ligament (ACL)-deficient knee. The pivot shift test's subjective grading scale can be quantified and refined using image analysis techniques.

The present invention acquires a microscopic image (201) obtained by photographing the surgical member (121) inserted to the subject with a surgical microscope (112), estimates the relative posture of the surgical member in the subject on the basis of the acquired microscopic image (201), and outputs posture information (222, 223, 224) associated with the posture that has been estimated. The present invention can be applied to ophthalmic surgery, in which an intraocular endoscope or surgical tool is observed with a surgical microscope, for example.

Abstract: Physicians performing invasive procedures utilize instruments inserted into a human body to perform the procedures. Such procedures typically involve actions to be performed on specific targeted anatomical structures. During the procedure, nearby anatomical structures unrelated to the procedure should generally be avoided. A system and techniques are provided herein for monitoring the position of such unrelated nearby anatomical structures relative to one or more surgical instruments. The system emits a warning to a human operator such as a surgeon if one of the instruments is too close to a monitored anatomical structure.
