Abstract: Method and system are provided for direction guidance of an endoscopic device in a tubular organ. The method receives a current image frame from a camera disposed on the endoscopic device, where the current image frame captures a visible lumen of the tubular organ. The method determines an area of the visible lumen in the current image frame and a ratio of the area of the visible lumen to a minimum enclosing circle of the visible lumen. If the ratio breaches a defined threshold, the method adjusts a target direction of the endoscopic device in a direction from a center of the visible lumen towards a center of the image frame and outputs a notification of the adjusted target direction to a controller of the endoscopic device.

Abstract: A computer-implemented method for generating code for real-time stream processing, where data is streamed in tuples. One or more processors receive source code which includes code to be applied in a sequential series to one or more tuples. Processor(s) generate the code for real-time stream processing by: buffering received time sequence tuples in a buffer; and converting the code to be sequentially applied to the one or more tuples into code for buffered tuples with a loop construct. Processor(s) also generate code for: checking that all tuples in a processing window have been buffered; and applying the converted code to each tuple in the processing window.

Abstract: A computer-implemented method for generating code for real-time stream processing, where data is streamed in tuples, and where each tuple has a timestamp and a value. One or more processors receive source code. The source code includes: code to be applied in a sequential series to one or more tuples; a definition of a size of a sequence of tuples to be processed as a processing window; and a size of a sequence of earlier tuples that a current tuple depends upon as a dependence window. Processor(s) generate the code for real-time stream processing by: buffering received time sequence tuples in a buffer in accordance with the processing window and the dependence window; and converting the code to be sequentially applied to the one or more tuples into code for buffered tuples with a loop construct.
