Video Sequence Point Processor - Screenshots
1) Download and unzip the ZIP archive below and unzip the folder to an appropriate place on your hard disk.
2) The program expects to find data in the same directory. It will search
for and list folders with an underscore in their name. So, put each set of
images in a folder named with the format, for example, SUBJECT_NUMBER; just
so long as it includes at least one underscore.
3) To run the program double-click the file Grab.exe. (Grab-debug.exe opens
a command window so you can see and report messages from the workings of the
program if anything goes wrong).
4) Select a data set using the drop-down menu in the top left (populated
with the names of all folders in the program directory with an "_" in them).
5) Press space to go to the first image.
6) Position the cursor over the marker on top of the target and right-click.
This places a red cross at that point. The point will only register is the
mouse is still when clicked, so don't rush - stop and click. The coordinates
appear below the image.
7) Position the cursor over the cross location and left-click. This places a
blue cross at that point. The point will only register is the mouse is still
when clicked, so don't rush - stop and click. The coordinates appear below
Stages 6 & 7 are interchangeable - either can be done first. If either point
is not visible then you don't need to mark it: a non-clicked point will be
recorded as 0,0 in the data file.
If you are not happy with either point you can re-click (might be best to
click somewhere away from the point to give a clear view, then click on the
point you want to mark) or press the Esc key and re-mark both points.
8) When you are happy with both points (even if that means omitting one or
both), press the space bar and the coordinates will be written to the output
file and the next image in sequence will be displayed until the last image
has been processed.
At the end of the sequence in a tab-delimited text file in the same
directory as the images themselves. This can be imported into Excel or any
other program. To open directly in Excel, just replace the .txt on the end
of the file name with .xls .
A test folder of five images is included in the folder AH_D00.
Download a ZIP archive containing the .class files for this application along with an executable wrapper (Grab.exe) and example images..
