Providing Evidence for the Null Hypothesis in Functional Magnetic Resonance Imaging Using Group-Level Bayesian Inference

open access: yesFrontiers in Neuroinformatics, 2021
Classical null hypothesis significance testing is limited to the rejection of the point-null hypothesis; it does not allow the interpretation of non-significant results. This leads to a bias against the null hypothesis.

Unified Lowering Decision of Parametric Thinning in the Hypothesis Test Framework

open access: yes2015 International Conference on Digital Image Computing: Techniques and Applications (DICTA), 2015
Homotopic grayscale thinning leads to over-connected skeleton when applied on noisy images. To avoid this phenomenon, the parametric thinning relaxes the initial constraint by lowering low contrast crests, peaks and ends, according to a parameter related to the noise and contrast of the image and under the constraint of ascendant gray level processing.
