A method of lung lobe segmentation having the steps of: providing of three dimensional first image data of a lung; segmentation of a tubular structure to identify first voxels of the first image data belonging to the tubular structure and to identify second voxels of the first image data which do not belong to the tubular structure; determining a distance measure for each one of the second voxels, by determining a minimum distance between each one of the second voxels to one of the first voxels to provide second image data; and performing a lobe segmentation based on the second image data.

A method has been described for deriving contour data in X-Ray images for vessels with differential absorption through applying a contour-finding algorithm on a shadow image and finding the vessel borders through segmentation based on image intensities. In particular, the method uses the following steps: finding a densitometric area of an above mentioned vessel, and displacing one or both of the borders inward until the densitometric measurement result between the borders after such displacing will start to change significantly. Furthermore, a specific procedure is introduced to automatically determine the conversion factor to equate the densitometrically based diameter to the contour based diameter of the vessel and to discriminate bifurcating or parallel vessels.

A method is provided for determining analyte concentrations, for example glucose concentrations, that utilizes a dynamic determination of the appropriate time for making a glucose measurement, for example when a current versus time curve substantially conforms to a Cottrell decay, or when the current is established in a plateau region. Dynamic determination of the time to take the measurement allows each strip to operate in the shortest appropriate time frame, thereby avoiding using an average measurement time that may be longer than necessary for some strips and too short for others.

Thin-film thickness and refractive index are measured using the Fourier amplitude of a broadband interferometric spectrum. Due to the smooth nature of the Fourier amplitude as a function of wavelength, as compared to the fast varying Fourier phase conventionally used to measure thickness, increased stability and repeatability of measurement are achieved. As a result, measurements of ultra-thin films with thickness below 100 nm are possible with reliable results.

A method of generating a susceptibility map of an object utilizes a regularizing inverse function, oversampling k-space, removing external phase noise and rapid phase change effects, accounting for the known geometry of the object, and using modified SWI phase data to generate reasonable susceptibility maps and digital images therefrom, such as SWI images. The inventors refers to the inventive methods set forth herein as Susceptibility Weighted Imaging and Mapping (SWIM).

A lane recognizing image processing system for recognizing lane markings laid on a driving road for motor vehicles includes a lane marking candidate point extraction means (20) for extracting lane marking candidate points (C) from an image (G) taken by an image pickup means (10) mounted on the motor vehicle, and a lane recognizing means (30) for recognizing a lane defined on the road on the basis of set of the lane marking candidate points (C). The lane recognizing means (30) includes a lane marking candidate point position converting means (31) for recognizing as lane marking candidate point positions the positions of the lane marking candidate points (C) transformed onto a straight line extending toward a null point.

A method for intraoral imaging obtains a digital image of one or more teeth and detects first and second boundaries. At each of the first and second boundaries, there is calculated a boundary ratio of mean gray-scale values for the tooth area on one side of the boundary to mean gray-scale values for background areas on the other side. The calculated boundary ratios are stored. A third ratio of the mean gray-scale values for the tooth area near the first boundary to the mean gray-scale values for the tooth area near the second boundary is calculated and stored. A vector is formed and stored that contains at least the calculated boundary ratios and the third ratio. The tooth surface is classified as either smooth or occlusal according to the stored vector. The image data is processed according to the classification and processing results are reported.

The invention aims at separating a background area of an image using a plurality of cameras by utilizing a method of estimating a background in combination with a stereo method. Data on input images, synchronous with one another, which are obtained by photographing images of a subject from different points of sight using at least two cameras is stored in a frame memory. A background area estimation processing unit performs global image superimposition for the input images, synchronous with one another, the data on which is stored in the frame memory on the assumption that a background area is in the distance and has a flat surface. Then, the background area estimation processing unit estimates the background area based on a degree of local similarity. A distance image generation processing unit performs distance measurement with respect to points other than those in the estimated background area by utilizing a stereo method to generate distance images. A background separated image generation processing unit removes the image of an area in a predetermined distance or more from the input images by referring to resulting distance images to generate a background removed image.

A set of images is processed to modify and register the images to a reference image in preparation for blending the images to create a high-dynamic range image. To modify and register a source image to a reference image, a processing unit generates correspondence information for the source image based on a global correspondence algorithm, generates a warped source image based on the correspondence information, estimates one or more color transfer functions for the source image, and fills the holes in the warped source image. The holes in the warped source image are filled based on either a rigid transformation of a corresponding region of the source image or a transformation of the reference image based on the color transfer functions.

Methods and systems are presented to analyze a retinal image of an eye and assigns features to known anatomical structures such as retinal layers. One example method includes receiving interferometric image data of an eye. A set of features is identified in the image data. A first subset of identified features is associated with known retinal structures using prior knowledge. A first set of characteristic metrics is determined of the first subset of features. A second set of characteristic metrics is determined of a second subset of features. Using the characteristic metrics of the first and the second sets, the second subset of features is associated with the retinal structures. Another example method includes dividing interferometric image data into patches. The image data in each patch is segmented to identify one or more layer boundaries. The segmentation results from each patch are stitched together into a single segmentation dataset.
