However, their solver is sensitive to a parameter termed as Lipschitz constant, which is computational load during the template updating.
The remaining two trackers IVT and L1 cannot cope with severe appearance changes, since the ground truth is not preserved in their template updating.
But for the template updating, we only apply the second criterion with a stricter threshold, i.e., ( left|right|{beta}_{G_p}Big|{Big|}_1/Big|left|beta right|{Big|}_1>0.8 ), which provides more reliable features and then prevents the template from identity drift.
Then, the outliers can be easily excluded from the template updating, if a relatively strict threshold is adopted, e.g., ( left|right|{beta}_{G_p}Big|{Big|}_1/Big|left|beta right|{Big|}_1>0.8 ).
The "occlusion flag" signals whether the corresponding bounding box is occluded, and then triggers the stochastic mechanism to enlarge the objects' search area to accommodate possible trajectory changes during occlusions, meanwhile stops the template updating to prevent the model from being corrupted by irrelevant data.
As the technology matures, users demand better performance against non-ideal (poor) biometric signals, e.g., border crossing systems should be able to capture the biometric signal of the iris or face while patrons are moving or computers should be able to authenticate patron credentials 10 years or more after enrollment without the requirement of template updating.
The present paper addresses the problem of knowledge templates update in product design.
Results are discussed in terms of plasticity of kin recognition systems, the costs and benefits of maintaining social memories, and the contexts in which templates are updated.
Thus, new landmark positions are predicted in the light of the image and the joint shape model, and then templates are updated by sampling from the training images.
To follow the gradual changes that are common in physiological signals, the template is updated regularly.
