Validation of Shape Context Based Image Registration Method Using Digital Image Correlation Measurement on a Rat Stomach

Figure 2

The stomach surface at distension pressure of 0.0 kPa (a), 0.2 kPa (b), 0.4 kPa (c), and the calculated 3D displacement distribution at pressure 0.4 kpa (d). The colour areas in figures (b) and (c) are DIC measured full-field strain distributions where images were obtained from the DIC system. The displacement distribution in (d) was calculated from (1), by using the DIC system recorded 3D coordinates of each correspondence surface point pairs between the reference surface (pressure = 0.0 kPa) and the target surface (pressure = 0.4 kPa). Colours from blue to red represent increasing values.
