Enhanced robust spatial feature selection and correlation filter learning for UAV tracking.

Spatial boundary effect can significantly reduce the performance of a learned discriminative correlation filter (DCF) model. A commonly used method to relieve this effect is to extract appearance features from a wider region of a target. However, this way would introduce unexpected features from background pixels and noises, which will lead to a decrease of the filter's discrimination power.

Process Evaluation of an Implementation Trial: Design, Rationale, and Early Lessons Learnt From an International Cluster Clinical Trial in Intracerebral Hemorrhage.

Background: The third INTEnsive care bundle with blood pressure Reduction in Acute Cerebral Hemorrhage Trial (INTERACT3) is an ongoing, international, multicenter, stepped-wedge cluster, prospective, randomized, open, blinded endpoint assessed trial evaluating the effectiveness of a quality improvement "care bundle" for the management of patients with acute spontaneous intracerebral hemorrhage (ICH) in low- and middle-income countries (LMICs). An embedded process evaluation aims to explore the uptake and implementation of the intervention, and understand the context and stakeholder perspectives, for interpreting the trial outcomes.

Methodology: The design was informed by Normalization Process Theory and the UK Medical Research Council process evaluation guidance.

Implementing a Goal-Directed Care Bundle after Acute Intracerebral Haemorrhage: Process Evaluation for the Third INTEnsive Care Bundle with Blood Pressure Reduction in Acute Cerebral Haemorrhage Trial Study in China.

Background: The third INTEnsive care bundle with blood pressure Reduction in Acute Cerebral Haemorrhage Trial is an ongoing international, multicentre, stepped wedge, cluster-randomized trial to determine the effectiveness of a goal-directed care bundle (early intensive blood pressure [BP] lowering, glycaemic control, treatment of pyrexia, and reversal of anticoagulation), as compared to standard of care, on patient-centred outcomes after acute intracerebral haemorrhage (ICH). An embedded process evaluation aims to identify factors related to the uptake and implementation of the intervention. Herein, we present the process evaluation results for hospital sites in China.
