Heart Tracking – Arrows Drawn Pixel by Pixel
Filed under:
ather than use the line function in Octave I’ve created a function that can draw several types of arrow, either with colour gradients or uniform, thick or thin (these are parameterised). I’ll soon publish the code.
The shown above arrows are very tiny, but there is a small arrowhead that tells which direction the points move in. Additionally, I have been implementing some 3-D means of visualising what is being done, but it is too early to show the results of this, possibly with arrows in hyperspace too.
These new exemplary images show a surface yielded with ‘hot’ colours where I move landmark points in between frames. It’s still work in progress.
