hi. I tried to run the demo, but an error ocurred. here is the error:
Error using ShapeInserter/step
The Image input has 1 color planes and the Pts input has 0 shapes. The Color
value(s) parameter must be either a scalar providing one color for all shapes, or
a 0-element vector providing one color for each shape.
Error in detectFaceParts (line 129)
bbX = step(shapeInserter, bbX, bb);
Error in demo (line 9)
[bbox bbimg faces bbfaces] = detectFaceParts(detector,img,2);
would you please tell me why?
