Abstract: A display control apparatus performs overlapping display of a highlight image against a notification object that is visually recognized through a picture projection plane of a virtual image display apparatus used by a driver of a vehicle such that the highlight image represents the notification object. A target information acquisition section acquires target information including at least a position and a size of the notification object. A display execution section displays a first highlight image and a second highlight image in a display form capable of identifying each of the first highlight image and the second highlight image based on target information acquired by the target information acquisition section. The first highlight image corresponds to a size of the notification object, while the second highlight image results from enlarging the first highlight image at a predetermined magnification percentage.

Abstract: At least some embodiments of the present disclosure feature systems and methods for assessing the impact of visual features within a region of a scene. With the input of a visual representation of a scene and at least one selected region within the scene, the system applies a visual attention model to the visual representation to determine visual conspicuity of the at least one selected region. The system computes feature-related data associated with a plurality of features of the at least one selected region. Based on the visual conspicuity and the feature-related data, the system assesses an impact that at least one of the features within the at least one selected region have on the visual conspicuity.

Abstract: Comparing extracted card data from a continuous scan comprises receiving, by one or more computing devices, a digital scan of a card; obtaining a plurality of images of the card from the digital scan of the physical card; performing an optical character recognition algorithm on each of the plurality of images; comparing results of the application of the optical character recognition algorithm for each of the plurality of images; determining if a configured threshold of the results for each of the plurality of images match each other; and verifying the results when the results for each of the plurality of images match each other. Threshold confidence level for the extracted card data can be employed to determine the accuracy of the extraction. Data is further extracted from blended images and three-dimensional models of the card. Embossed text and holograms in the images may be used to prevent fraud.

Abstract: A computed tomography (CT) apparatus includes a reconstruction unit which reconstructs a first CT image corresponding to a field of view (FOV) by using a first sinogram acquired by a CT scan of an object; and a correction unit which acquires a second sinogram by performing forward projection on the first CT image and acquires a second CT image by using the second sinogram and a third sinogram representing a portion of the object that is not included in the FOV. Thus, the CT apparatus reduces generation of image errors to thereby provide a high-quality reconstructed CT image.

Abstract: A system for detecting clouds and cloud shadows is described. In one approach, clouds and cloud shadows within a remote sensing image are detected through a three step process. In the first stage a high-precision low-recall classifier is used to identify cloud seed pixels within the image. In the second stage, a low-precision high-recall classifier is used to identify potential cloud pixels within the image. Additionally, in the second stage, the cloud seed pixels are grown into the potential cloud pixels to identify clusters of pixels which have a high likelihood of representing clouds. In the third stage, a geometric technique is used to determine pixels which likely represent shadows cast by the clouds identified in the second stage. The clouds identified in the second stage and the shadows identified in the third stage are then exported as a cloud mask and shadow mask of the remote sensing image.

Abstract: Presented herein are efficient and reliable systems and methods for calculating and extracting three-dimensional central axes of bones of animal subjects—for example, animal subjects scanned by in vivo or ex vivo microCT platforms—to capture both the general and localized tangential directions of the bone, along with its shape, form, curvature, and orientation. With bone detection and segmentation algorithms, the skeletal bones of animal subjects scanned by CT or microCT scanners can be detected, segmented, and visualized. Three dimensional central axes determined using these methods provide important information about the skeletal bones.

Abstract: Various embodiments may increase scalability of image representations stored in a database for use in image matching and retrieval. For example, a system providing image matching can obtain images of a number of inventory items, extract features from each image using a feature extraction algorithm, and transform the same into their feature descriptor representations. These feature descriptor representations can be subsequently stored and used to compare against query images submitted by users. Though the size of each feature descriptor representation isn't particularly large, the total number of these descriptors requires a substantial amount of storage space. Accordingly, feature descriptor representations are compressed to minimize storage and, in one example, machine learning can be used to compensate for information lost as a result of the compression.

Abstract: When recognizing leads by processing an image captured by a camera of a component provided with a single row or multiple rows of leads of the same size and shape at a regular pitch, waveform analysis of a change pattern of brightness (pixel value) along multiple lines set in a vertical, a horizontal, or a diagonal direction of the image is performed so as to identify a region in which the brightness changes cyclically as a lead recognition target region in which there is a possibility of a lead existing. Then, image recognition of leads is performed in the lead recognition target region.

Abstract: Three-dimensional image data of an imaged object, such as the bone structure of a patient, comprise first and second rigid parts movably connected to each other, in a first state of position and orientation. Sub-regions within the three-dimensional image data are divided into at least first image data and second image data.

According to one embodiment, an apparatus includes histogram stretching logic to generate a stretched histogram. The stretched histogram is generated by compressing an enlarging a contrast of brightness bins of an equalized histogram of brightness component values formed from a previous input frame of image pixel data.

Noise detection logic classifies the flat pixels as being noisy pixels or non-noisy pixels, and counts a number of the noisy pixels. The number of noisy pixels and characteristics of the stretched histogram are used to enhance the contrast of a current input frame of image pixel data.

Abstract: A system that provides an improved way of scheduling a plurality of imaging tasks in a medical imaging system is disclosed. The system enables a user (i.e. a technician or medical expert) to group different imaging tasks and executes them simultaneously to significantly reduce scan time. These imaging tasks are of different types or are related to different imaging techniques. If different imaging tasks need to be performed substantially at the same location and have substantially same scan time then they can be scheduled simultaneously so that overall scan time can be reduced.
