摘要： This invention concerns the tracking of objects in video data for artificial vision; for instance for a bionic eye. More particularly, the invention concerns a vision enhancement apparatus for a vision-impaired user. In other aspects, the invention concerns a method for enhancing vision and software to perform the method. The image processor operates to process video data representing images of a scene. Automatically detect and track a user selected object, such as a face, in the images. And, automatically modify the video data, by reserving a user selected area of the displayed images for displaying the tracked object as a separate video tile within the scene. The separate video tile remains in the selected area despite movement of the camera relative to the scene, or movement of the user relative to the object or the scene.

摘要： The invention concerns representing three-dimensional surface information of an object appearing in an' electronic image (14), such as for medical diagnostic purposes. A partitioning module (14a) partitions (200) the object into multiple three-dimensional parts. A representation module (14b) determines for each part a representation (202) of the three- dimensional surface of that part using a scale space analysis of the shape index and curvedness of the surface of that part. The representation offers a complementary understanding of the nature of the shape of the object using a shape index and curvedness for surface description, a scale space analysis of the surface and a, localisation of that analysis through a partitioning of the surface. The resulting representation is specific to particular regions ( i.e. parts) of the shape. In this way the representation is not a single global descriptor of the shape of the object. By being specific to particular regions the representation of the surface is better able to capture subtle differences in the shape classes ( i.e. roughness vs smoothness).

摘要： This disclosure concerns a method for enhancing vision for a vision impaired user comprises. A processor, such as a controller of a retinal prosthesis, determines based on input image data a shape associated with an object represented by the input image data. The processor then determines for each of multiple areas of the input image data a coverage value that indicates to what extent the shape covers that area of the input image. Each of the multiple areas is associated with one of multiple imaging elements of the retinal prosthesis. The processor then determines an output value for each of the multiple imaging elements of the retinal prosthesis, such that when the output values are applied to the imaging elements to create a visual stimulus, a contrast is perceivable between a first element and a second element based on their respective coverage values.

摘要： This disclosure concerns the determination of low dynamic range image data from high dynamic range image data. A processor determines the low dynamic range image data by optimising a degree to which the low dynamic range image data satisfies a local contrast constraint and a global consistency constraint. The local contrast constraint is based on a local contrast in a perception space while the global consistency constraint is based on a relationship between points in the high dynamic range image data. The determined low dynamic range image data preserves the local contrast from the high dynamic range image data while also preserving the relationship between points in the high dynamic range image data to a high degree. As a result, the method prevents contrast distortion, halos and artifacts and ordering of level lines (isocontours) is preserved.
摘要翻译：本公开涉及从高动态范围图像数据确定低动态范围图像数据。处理器通过优化低动态范围图像数据满足局部对比约束和全局一致性约束的程度来确定低动态范围图像数据。局部对比约束基于感知空间中的局部对比度，而全局一致性约束基于高动态范围图像数据中的点之间的关系。确定的低动态范围图像数据保持来自高动态范围图像数据的局部对比度，同时还高度保持高动态范围图像数据中的点之间的关系。因此，该方法可以防止对比度失真，光栅和伪影以及等级线（异形体）的排序。
