Data transmission in remote computer assisted detection
First Claim
1. In a non-transitory computer readable storage medium having stored therein data representing instructions executable by a programmed processor for data transmission in computer assisted detection, the storage medium comprising instructions for:
- receiving, at a computer assisted detection processor and from the remote storage location, first data, the first data comprising down sampled data of data representing a region;
detecting, by the computer assisted detection processor, a plurality of first locations of a spatial aspect of structure represented by the first data;
requesting and receiving, at the computer assisted detection processor, second data, the second data comprising additional data representing second neighborhoods around the first locations and not representing portions of the region outside of the second neighborhoods;
detecting, by the computer assisted detection processor, a plurality of second locations of the spatial aspect of the structure represented by the second data; and
outputting positions to a client device different than the computer assisted detection processor and the remote storage location, the positions being a function of the second locations.

Abstract
For cloud-based computer assisted detection, hierarchal detection is used, allowing detection on data at progressively greater resolutions. Detected locations at coarser resolutions are used to limit the data transmitted at greater resolutions. Data is only transmitted for neighborhoods around the previously detected locations. Subsequent detection using higher resolution data refines the locations, but only for regions associated with previous detection. By limiting the number and/or size of regions provided at greater resolutions based on the previous detection, the progressive transmission avoids transmission of some data. Additionally, or alternatively, lossy compression may be used without or with minimal reduction in detection sensitivity.
