Described herein are catheters for use with Optical Coherence Tomography (OCT) that include an optical fiber core having a first refractive index and an interface medium having a second refractive index, where the first and second refractive indexes are mismatched such that receiving electronics configured to receive optical radiation reflected from the reference interface and the target operate in a total noise range that is within 5 dB of the shot noise limit. These OCT catheters may include a silicon die mirror having a reflective coating that is embedded in the interface medium. The optical fiber can be fixed at just the distal end of the catheter, and may be managed within a handle that is attached to the proximal end of the catheter body, and is configured to allow rotation of the both catheter body and the optical fiber relative to the handle.

A system and method for tomographic image reconstruction using truncated limited-angle projection data that allows exact interior reconstruction (interior tomography) of a region of interest (ROI) based on the linear attenuation coefficient distribution of a subregion within the ROI, thereby improving image quality while reducing radiation dosage. In addition, the method includes parallel interior tomography using multiple sources beamed at multiple angles through an ROI and that enables higher temporal resolution.

Medical images are automatically segmented by customizing the morphological segmentation of features identified in the image based upon statistical analysis of the features within each region to be analyzed. The statistical description of the features, as reported through a feature vector, informs the system as to which input variables to select for further segmentation analysis for features residing within the region of the image analyzed. By customizing the automatic segmentation analysis to produce an enhanced image, features within the image are characterized more efficiently and precisely. False positive identification of lesions are minimized without sacrifice of true positive identifications.

Various implementations of the invention provide techniques and supporting systems that facilitate real-time or near-real-time ultrasound tracking for the purpose of calculating changes in anatomical features during a medical procedure. More specifically, anatomical features within a patient undergoing a medical procedure are tracked by obtaining temporally-distinct three dimensional ultrasound images that include the feature of interest and obtaining a targeted subset of ultrasound images focused on the feature. Based on the targeted subset of ultrasound images, a displacement of the feature is determined and image parameters used to obtain the targeted subset of ultrasound images are adjusted based on the displacement. This results in a time-based sequence of three dimensional images and targeted ultrasound images of the feature that identify changes in the position, size, location, and/or shape of the feature.

An image display device 100 includes: a display unit 10 having an image screen 11 for displaying a two-dimensional image; an image transfer panel 20 located on a path of light left from the image screen 11; a floating image display unit 1 that displays, as a floating image, the light left from the image screen 11 in a space located on one side of the image transfer panel 20 opposite to the other side thereof facing the display unit 10; a direct-view image display unit 2 provided with a display unit 40 having an image screen 41 for displaying a two-dimensional image displayed on the image screen 41 as a direct view image. The image display device carries out:

• • floating-image control that displays the floating image P2 such that the given object displayed as the floating image P2 is shifted in a specified first direction from the displayed position of the floating image P2 to the image screen 41; and
  • direct-view image control that executes a process associated with the given object during or after the shift of the given object, and displays, on the image screen 41, a two-dimensional image on which the executed process is reflected.

An object of the invention is to provide an apparatus which performs correction only to a high-brightness portion generated in a particular region, in which a decrease in brightness is necessary, and glaze is removed or reduced. A correction process in which the brightness or the lightness is decreased is simply performed to a pixel in which the brightness or the lightness is high, but a predetermined region (for example, face, eyes, and mouth) of a subject is detected and a degree of correction of each pixel is determined based on the detection result (a position and a color of the predetermined region). Therefore, the region in which the decrease in brightness is not necessary is maintained at high brightness, and the image correction is performed only to the region in which the decrease in brightness is necessary (for example, the region in which the glaze of a skin is generated).

An imaging method for imaging a subject (18) including fibrous/anisotropic structures (102) includes acquiring three-dimensional image representations without and with a plurality of different diffusion weighting and directions. When a user (56) hovers a selection device over a voxel of the image, a fiber representation (54) is extracted in substantially real time. The representation is generated by following a direction of a major eigenvector e₁ from voxel to voxel. A human-viewable display of the fiber representation is produced (210).

Methods and apparatus for spectrally-encoding plural source images and for providing the spectrally-encoded plural source images in a composite image, for rendering the composite image in a physical form, or for recovering at least one of the encoded source images from the rendered composite image such that the recovered source image is made distinguishable. The composite image is generated using an image-dependent dynamic range determination so as to provide a maximum usable contrast in a recovered source image.

In the image processing of color image, color image data are received, and the color image data are corrected to maximize an overlapping quantity of histograms of the image data on a plurality of colors. Alternatively, color image data are received, and histograms of a plurality of colors on the color image data are calculated. Then, color deviation of image is corrected to maximize an overlapping quantity of the histograms. Alternatively, color image data are received, and color fog is detected on the color image data and a color of the color fog is determined. Then, the image data of the color on which color fog is detected is decreased. Alternatively, color fog is detected in an input color image data; and a color of the detected color fog is displayed. Alternatively, color fog of input image is corrected first, and contrast on the image is corrected next.

A cross-media search method using a VGG convolutional neural network (VGG net) to extract image features. The 4096-dimensional feature of a seventh fully-connected layer (fc7) in the VGG net, after processing by a ReLU activation function, serves as image features. A Fisher Vector based on Word2vec is utilized to extract text features. Semantic matching is performed on heterogeneous images and the text features by means of logistic regression. A correlation between the two heterogeneous features, which are images and text, is found by means of semantic matching based on logistic regression, and thus cross-media search is achieved. The feature extraction method can effectively indicate deep semantics of image and text, improve cross-media search accuracy, and thus greatly improve the cross-media search effect.

A method for generating a stabilized three-dimensional image from a scannerless range imaging system comprises the steps of acquiring a bundle of three or more phase offset images corresponding to modulated illumination reflected from a scene, whereby one or more of the phase offset images includes image motion relative to another phase offset image; searching for a stable chain of phase offset images in the image bundle, wherein a stable chain is a collection of images that is obtained by testing the phase offset images against a confidence measure that separates less severe correctable image motion from more severe image motion and then populating the stable chain only with those phase offset images that meet the confidence measure for correctable image motion; correcting for the image motion in the stable chain of images if a stable chain of at least three phase offset images is found to exist; and computing a stabilized three-dimensional image using the phase offset images from the stable chain of phase offset images.

A first digital colour image with pixels having colour values is transformed to a second digital colour image with pixels having transformed colour values, the colour values being defined in a selected colour space. Pixel clusters are formed for the first digital colour image whereby pixels of a pre-defined category are grouped into a particular cluster in the selected colour space. The colour values of the pixels in a particular cluster are transformed such that transformed colour values belong to a pre-defined area associated to the particular cluster in the selected colour space, the pre-defined area consisting of memory colours of the same pre-defined category. The second digital colour image can be rendered on a display screen or on a print medium.
