Figure 3
A screen shot of the frame_viewer GUI. The x and y coordinates of the sample translations (Δxn) are displayed as both line plots (bottom panel) and a scatter plot (top right panel). The sample position corresponding to the current image is indicated by the vertical yellow line and the blue dot, respectively. The current image is displayed in the top left panel, which will be divided by the white-field image, if present, in order to increase the contrast. One can scroll through the images by dragging the yellow line. Rather than read the entire data set into system memory, each image is read from file in real time so that very large data sets can be accommodated. The white rectangle in the top right panel can be used to select several frames to exclude from further analysis. The good (red dots) and bad (grey dots) status of a frame can also be toggled with the left mouse button.
