what method I should use for multi class object detection and recognition

edit

Could anyone suggest me for the method for multi class object detection and recognition in video? the background of video is not static environment. It is better if the method can perform more than 10 frames per sec.

the objects are ball in various color, fake snake toy, fake spider toy, and panda doll.

what method should I use BOVW or Haar Features or another method? sample images
