What types of analysis can i perform on the videos of drawings?

Hello,

I am doing an explatory research where as an investigation of the treatment on movement,II have asked subjects to draw on a drawing tablet and I am recording the videos of the drawings. I will do image analysis to the final drawings, such as color distributions, object analysis, box counting and fractal analysis.

For video analysis, I found that I can look at optical flow. Is there any other analysis can I do for the videos of the creation of drawing?

I would appriciate if you have any further suggestions for image processing too.

All my Best,

Hello,

For video analysis of the creation of drawings, besides optical flow, you can also consider the following techniques:

• Motion tracking: You can track the movement of specific points or objects in the video over time. This can be useful for analyzing the trajectory or speed of the process. Documentation: https://in.mathworks.com/help/vision/tracking-and-motion-estimation.html
• Gesture recognition: If you are interested in analyzing specific gestures or patterns in the drawings, you can use techniques like template matching or ML algorithms to recognize and classify different gestures. Documentation: https://in.mathworks.com/help/deeplearning/ug/gesture-recognition-using-deep-learning.html
• Time-lapse visualization: You can create a time-lapse video of the drawing process by extracting key frames at regular intervals. This can provide a condensed view of the entire drawing process. Documentation: https://in.mathworks.com/help/imaq/creating-time-lapse-video-using-timer-events.html

For image processing of the final drawings, in addition to the techniques you mentioned (color distributions, object analysis, box counting, and fractal analysis), you can also consider:

• Edge detection: Detecting and analyzing the edges of objects in the drawings can provide insights into the overall structure and composition.Documentation: https://in.mathworks.com/discovery/edge-detection.html
• Texture analysis: Analyzing the texture patterns in the drawings can help in understanding the artistic style or brushstroke techniques used by the subjects. Documentation: https://in.mathworks.com/help/images/texture-analysis-1.html

I hope these suggestions are helpful for your research
