Methods and systems are provided for measuring a retinal sublayer characteristic of an eye. A plurality of axial scans are performed over an area of the retina of the eye. Reflections are measured during the axial scans to determine a plurality of sets of reflection intensity values. A given set of reflection intensity values is associated with one of the plurality of axial scans. A progressive refinement boundary detection algorithm is performed using the plurality of sets of reflection intensity values to determine at least one boundary location associated with the retinal sublayer for each of the plurality of sets of reflection intensity values. The retinal sublayer characteristic is determined in response to the determined boundary locations.

A method and apparatus to confine and constrain an animal or human subject to a specific area has the capability to change the borders of the restraint area remotely to maximize an area's utility. A collar or support is placed on the subject; the collar carries an electronic module to receive and send signals and to activate a restraining or feedback mechanism. In its simplest form, the collar receives and transmits Global Positioning System (GPS) data to be matched against a preset group of boundary coordinates. The system of the present invention utilizes GPS location technology to define the boundary. When the input matches the boundary coordinates set into the receiver, an impulse is delivered to the subject or wearer. This impulse becomes increasingly severe as the wearer moves farther away from the boundary point. Upon return to the boundary location the impulse ceases and, as long as the wearer stays within the boundaries, no further impulse is imparted. Terrain of the designated area is not a factor in the operation of the system since it can be programmed for use anywhere. The coordinates of the boundaries can either be preset or remotely changed to redefine the permitted areas.

Systems and methods that accurately detect and locate an edge or boundary position based on a number of different characteristics of the image, such as texture, intensity, color, etc. A user can invoke a boundary detection tool to perform, for example, a texture-based edge-finding operation, possibly along with a conventional intensity gradient edge-locating operation. The boundary detection tool defines a primary region of interest that will include an edge or boundary to be located within a captured image of an object. The boundary detection tool is useable to locate edges in a current object, and to quickly and robustly locate corresponding edges of similar objects in the future.

A boundary detector includes a candidate line detecting unit that detects a candidate line of a lane boundary position drawn on a road surface based on image data of a predetermined detection time period acquired from a camera. The detector also includes a lane boundary position selecting unit that selects a lane boundary position based on the candidate line; a branch lane boundary position selecting unit that selects a lane boundary position of a branch lane that diverts from a main lane based on the candidate line; and a branch processing unit that sets a branch process mode in which the detection time period is short without using the selected lane boundary position of the branch lane when the branch lane boundary position selecting unit selects the lane boundary position of the branch lane.

A device for monitoring the surrounding area is provided in a self-propelled working machine, which is provided with a working means, and an operation means at a position near a driver's seat of a revolving structure and performs predetermined work, and monitors the area around the working machine, the device having a configuration provided with: a plurality of cameras which are provided in the revolving structure, two cameras each being installed such that parts of viewing fields thereof overlap each other; an image transform means which generates virtual viewpoint images by viewpoint-transforming camera images acquired by the respective cameras such that the camera images become top-view images; an image synthesis means which sets, on a monitor, the display regions of the virtual viewpoint images captured by the respective cameras and displays the respective virtual viewpoint images in the display regions; and a display form change means which changes the boundary positions between the display regions of the respective virtual viewpoint images.
