A change tracking and delta generation (CTDG) system servicing multiple clients is disclosed for enabling the delta generation during replication to be proportional to the number of changes between two snapshots instead of the size of the snapshots. In some embodiments, CTDG can track changes to a file system, where change-tracking can be dynamically switched between two sub-CT modes, file level or directory level. Change-tracking (CT) keys may be generated accordingly and stored in a data structure to be used for delta generation during replications for clients. In some embodiments, change-tracking may be enabled or disabled for different clients. CTDG can coordinate the CT enablement / disablement to ensure replications can use the information in CT keys properly.

This invention relates to the field of image data processing technology and discloses a method and system for tracking and analyzing dynamic changes in the endometrium based on image registration. The method includes: extracting the boundary pixel coordinates of the target region in a first image frame and a second image frame, and constructing a discrete coordinate chain with a neighborhood index relationship; constructing a spatial distance field representing pixel spatial displacement constraints based on the target region of the second image frame; extracting the gradient vector of the discrete coordinate chain in the spatial distance field, and using second-order central difference to decouple the displacement bias into a normal driving component and a tangential homogenization component; generating a spatial deformation field through vector superposition, and performing coordinate resampling on the first image frame. This invention utilizes an orthogonal decoupling mechanism to decouple spatial mapping logic from pixel features, effectively constraining pixel distribution density during deformation, solving the problems of spatial folding and topological tearing under large-scale nonlinear deformation, and improving image tracking stability.

The present disclosure relates to the technical field of smart home device, and discloses a smart home device change tracking method and system, which detects the communication network level between the data source device and the subscription device and configures a differentiated benchmark push period accordingly, so that the push strategy is adapted to the link bandwidth and delay characteristics, thereby avoiding high-bandwidth link resource idling and low-bandwidth link overload congestion. By dynamically adjusting the benchmark push period according to the trust weight, and executing the push in an event-triggered manner when the device state changes, a mechanism is realized in which the tracking frequency is adaptively adjusted according to the link quality, and the state change can be synchronized without waiting for the period to expire, thereby reducing the redundant communication overhead caused by a static push strategy. By continuously feeding back the communication result of each push to the trust weight and readjusting the current push period, a closed-loop adaptive update of the tracking push strategy based on the measured communication quality is realized.
