摘要： Method for performing segmentation of an interior vessel within the body of a patient, the method including obtaining a sequence of intravascular ultrasound images of an interior vessel and dividing the sequence into batches, detecting uninformative regions in each of the batches, the uninformative regions arising from an acoustic shadow cast by guide wire and by calcified plaque within the interior vessel, extracting a preliminary outer boundary of the interior vessel, tracking images in each of the batches to counter various distortions, performing statistical analysis and spatial integration on each of the batches to obtain a classification of blood and tissue regions, extracting a secondary outer boundary of the interior vessel utilizing the classification of blood and tissue regions and refining result, and extracting the inner boundary of the interior vessel based on the classification of blood and tissue regions.

摘要： Method for performing segmentation of an interior vessel within the body of a patient (Fig. 1), the method including obtaining a sequence of intravascular ultrasound images of an interior vessel and dividing the sequence into batches (102), detecting uninformative regions in each of the batches (104), the uninformative regions arising from an acoustic shadow cast by guide and by calcified plaque within the interior vessel, extracting a preliminary outer boundary of the interior vessel (110), tracking images in each of the batches to counter various distortions (112), performing statistical analysis and spatial integration on each of the batches to obtain a classification of blood and tissue regions (118), extracting a secondary outer boundary of the interior vessel utilizing the classification of blood and tissue regions and refining result (120), and extracting the inner boundary of the interior vessel based on the classification of the blood and tissue regions.

摘要： In a process for rendering a 3-dimensional graphics scene made up of a plurality of static and/or dynamic objects composed of geometrical elements, a method for obviating redundant processing of hidden dynamic objects in successive images of the scene so as to accelerate the rendering of successive images of the scene. The method includes in respect of each hidden dynamic object: (a) predicting a time period during which the hidden dynamic object is assured to remain hidden; and (b) during the time period, not rendering the hidden dynamic object so as to output sensitively process the scene.
摘要翻译：在用于渲染由几何元素组成的多个静态和/或动态对象组成的三维图形场景的过程中，一种用于消除场景连续图像中的隐藏动态对象的冗余处理的方法，以便加速渲染连续的场景图像。该方法包括关于每个隐藏的动态对象：（a）预测隐藏的动态对象被保证保持隐藏的时间段; 和（b）在该时间段期间，不呈现隐藏的动态对象，以便敏感地输出处理场景。
