Explanation
This requirement is basically applying Zebra Stripes for Images into each frame of the video. Three optional sliders are also given to control the threshold value for each of the RGB component. Then, if the gray value falls within the zebra boundaries, that pixel’s component is set to the value determined by the slider.
The outcome is expected to be the same as Zebra Stripes for Images , except with the addition of colors to replace black. Below is a sample screenshot:
Hooray, green color!
1. What would be the use of such a filter for videos?
The use for this filter is similar to the previous requirement, except that it is applied on videos here. Additionally, colors can be used instead of using black color as done previously.
2. What kind of videos would best show the effect?
Videos with gradient! Yes, of course, the answer I wrote in the report is misleading. So after Mr. Rimi went through the trouble of making the gradient image I spoke about earlier into a video, I'd say such examples are the best to display the effect of zebra stripes. After all, a video is actually a collection of still frames aka images.
Reflection
I was thinking quite differently before Mr. Rimi showed us the gradient image & video. I was thinking more along the lines of... "if the background (like the wall in the image above) falls into the zebra category while the object (in this case, that handsome guy in the image) in the foreground doesn't, it'd show a difference". But when I think about it again, that'd only work if the objects in the foreground is simple in color....right?
