Upper bound on number of templates handled.

| uint32_t dwTemplateTrackerParameters::maxTemplateSize |
Maximum size of templates to track, if ROI > maxTemplateSize * maxTemplateSize, template tracker will clamp the center maxTemplateSize * maxTemplateSize region to do tracking.

| uint32_t dwTemplateTrackerParameters::numIterationsCoarse |
for DW_TEMPLATE_TRACKER_ALGO_IA only Iteration number to apply the coarse KLT for robustness.
Coarse tracking converges with smaller iteration number, but is not as accurate as fine tracking. If setting as 0, the algorithm will skip the coarse pass, use fine only iteration
Definition at line 141 of file TemplateTracker.h.
| uint32_t dwTemplateTrackerParameters::numIterationsFine |
Iteration number to apply the KLT tracker.
Definition at line 134 of file TemplateTracker.h.
| dwProcessorType dwTemplateTrackerParameters::processorType |
Processor type which determines on which processor the algorithm should be executed on.
Supported options are: DW_PROCESSOR_TYPE_GPU, DW_PROCESSOR_TYPE_PVA_0, DW_PROCESSOR_TYPE_PVA_1.

| float32_t dwTemplateTrackerParameters::thresholdKill |
Killing threshold in [0, 1].
If ZNCC between 2 frames is less than this value, tracking will be killed. Smaller value means less possible to be killed. If thresholdKill = 0 or -1, the tracking will not be marked as failure until it's out of time or move out of boundary. If thresholdKill = 1, the tracking will always be killed.
Definition at line 155 of file TemplateTracker.h.
| float32_t dwTemplateTrackerParameters::thresholdStop |
for DW_TEMPLATE_TRACKER_ALGO_IC only Stop threshold in [-1, 1].
If ZNCC between 2 frames is larger than this value, tracking will have early stop even before it reaches the maximal number of allowed iterations. Larger value means less possible to be considered as converged track. If nccThresholdStop = 1, the tracking will always run the maximal number of allowed iterations. If nccThresholdStop = -1, the tracking will run one iteration.
Definition at line 163 of file TemplateTracker.h.
| float32_t dwTemplateTrackerParameters::thresholdUpdate |
Updating threshold in [0, 1].
If ZNCC between 2 frames is less than this value, tracking template will be updated. Otherwise only updates its location but keep the original size and image data unchanged. Larger value means updating the template more frequently. If thresholdUpdate = 1, template will be updated every frame If thresholdUpdate = 0, template won't be updated unless the size of stored template and new one differs too much.

| float32_t dwTemplateTrackerParameters::validHeight |
Maximum valid template height, any templates with bbox.height > validHeight will be killed after tracking.
validHeight = -1.F means there's no height limitation
Definition at line 177 of file TemplateTracker.h.
| float32_t dwTemplateTrackerParameters::validWidth |
Maximum valid template width, any templates with bbox.width > validWidth will be killed after tracking.
validWidth = -1.F means there's no width limitation
