VideoProcessing — LSDVE OpenCV Video Annotation Tool

LSDVE (LSD Video Editor) is an OpenCV-based video annotation tool that makes video editing and annotation easier. It allows users to interactively draw and remove lines on video frames, saving the annotated results to a custom .lsd file format.

Supported Operations

• Right-click — pause/resume the video
• Left-click — select two points for a line (press down and press up)
• (A)dd — add a new line
• (R)emove — remove line in area selected by mouse
• (Q)uit & save — quit and save annotations
• (S)ave — save the current frame and advance to next
• (U)ndo — undo last action

Output Format

Annotations are stored in a .lsd file with this format:

frame:INT       <- frame number in the original video
lines:INT       <- number of lines in this frame
line1_X1,line1_Y1,line1_X2,line1_Y2
line2_X1,line2_Y1,line2_X2,line2_Y2
...
frame:INT
lines:INT
