Thermal images captured during recovery of diabetic feet after active cooling may reveal richer information than those from passive thermography, but diseased foot regions may exhibit very small temperature differences compared with the surrounding area, complicating plantar foot segmentation in such cold-stressed active thermography. In this study, we investigate new plantar foot segmentation methods for thermal images obtained via cold-stressed active thermography without the complementary information from color or depth channels.

Background: Hepatoblastoma (HB) is one of the most common cancers in children. Recent studies have shown that the occurrence of nuclear accumulation of β-catenin reaches 90%-100% because of the anomalous activation of the Wnt pathway in HB patients. Furthermore, emerging studies have shown that concomitant activated forms of YAP and β-catenin trigger the formation and progression of HB.
