Ratsnake: A Versatile Image Annotation Tool with Application to Computer-Aided Diagnosis

Figure 4

A snapshot of Ratsnake’s GUI. It displays the annotated kidney biopsy image of Figure 1(b). The user may click on the annotation names (labels) on the right and display the respective ROI. The labels used are semantic identifiers from the gene ontology [41]. Only the currently selected annotation can be displayed at a time, as a layer over the image to which it belongs. The dialog box is the result of the menu option Measurement→Area Measurement, which is used to measure the area of the current ROI. The panel on the left controls the parameters of the snake.
