Six slices with slice numbers a 1, b 3, c 5, d 7 , e 9 and f 11 from short axi MRI volume data from Department of Diagnostic Imaging of the Hospital for Sick Children in Toronto. g Variation of image features of each slice from the output of the low energy Gaussian filter at different Gaussian scales. h Variation of image features of each slice from the output of the high energy Gaussian filter at different Gaussian scales. i Contrast, sharpness and total quality scores of 15 slices from the MRI volume data
