Removed the necessity to append the detected object index (related to the frame) to the effect JSON - which makes the JSON smaller and the performance better.
Only show the tracked object's icon (on the mini-GUI to attach a clip to it) and transform handler if the object appears on the screen (i.e. it has data for the requested frame)
Added "has_tracked_object" property on EffectBase so that the AddEffect function checks for this property instead of the Tracker effect name - this way it's possible to support other effects that have tracked objects but different names.
Added new base class TrackedObjectBase, changed class KeyframeBBox to TrackedObjectBBox and changes it's inheritance from KeyframeBase to TrackedObjectBase.
- Added KeyframeBase class
- Adjusted the inheritance of KeyframeBase to KeyframeBBox and Keyframe
- Added feature to attach clip to bounding box
- Added support to select tracked object with a dropdown list and removed keyframebbox downcasting
Changed the bounding-box struct point convention to (cx, cy, width, height, angle).
The GetFrame member function from Tracker class now uses the cv::RotatedRect object to represent the bounding-box and draw it on screen.
The JSON and Protobuf communication between the backend and frontend still uses the (x1,y1)(x2,y2) point convention, the backend performs the adequate transformations.
-Moved the methods that handles protobuf data from Tracker to KeyframeBBox
-Displacement and scale keyframes are now properties of KeyframeBBox
-Changed interface that updates the KeyframeBBox properties.
It's now possible to adjust the tracked bounding box from the preview window. Some work is needed to make it generic to the ObjectDetection effect and future effects
