Solution Overview
Problem
Current target detection and tracking systems face inefficiencies in tracking multiple spots simultaneously, leading to increased calculation times, memory requirements, and false alarms, which can reduce detection range and accuracy.

Engineering Contradiction Analysis
1Reliability
If the detection threshold is increased to reduce false alarms, then the false alarm probability decreases, but the detection range is reduced
Solution Approach 1:
The patent applies preliminary action by pre-calculating statistical characteristics (mean, standard deviation, integrated intensity values) from previously processed images before analyzing the current image. This allows the system to establish baseline expectations for target presence and intensity distribution in advance, enabling more accurate detection decisions without requiring higher detection thresholds. The pre-computed statistics serve as reference data that guides the detection process, reducing false alarms while preserving detection range.
2Reliability
If tracking is performed for all detected spots, then the track detection probability improves, but the calculation time and memory requirements increase
Solution Approach 1:
The patent applies local quality by selectively applying tracking resources to specific spots based on their statistical significance. Instead of uniformly tracking all detected spots, the system evaluates each spot's intensity relative to the pre-computed statistical characteristics and prioritizes tracking for spots that exhibit target-like properties. This differentiated approach concentrates computational resources on the most promising candidates, maintaining high track detection probability while reducing overall calculation time and memory usage.
Solution Approach 2:
The patent changes parameters by using statistical metrics (integrated intensity values, standard deviations) to dynamically adjust tracking priorities. Spots with intensities that significantly deviate from the background statistics are assigned higher tracking priority. This parameter-based selection mechanism allows the system to adapt tracking resource allocation based on the actual content of each image, ensuring efficient use of computational resources while maintaining detection effectiveness.
3Reliability
If tracking is performed for all detected spots, then the track detection probability improves, but the system resource requirements increase
Solution Approach 1:
The patent applies local quality by selectively allocating memory resources for tracking based on the statistical properties of individual spots. Instead of pre-allocating memory for all possible spots, the system dynamically determines which spots warrant tracking memory allocation based on their intensity characteristics relative to the pre-computed statistical baseline. This selective memory allocation reduces overall memory requirements while ensuring sufficient resources are available for tracking statistically significant spots that are likely to represent actual targets.

AI summary
The invention relates to a method for detecting and tracking targets in a series of successive images, said method comprising limiting the number of spots which are the subject of simultaneous tracking or false leads. The operation of the tracking module is thereby improved without having to increase a detection threshold of said spots. The detection threshold can even be reduced, such that the detection haul is increased and the tracking of each target is more continuous, without the probability of false alarms itself being increased.
