Pretrained CNN(tensorflow/darknet/caffe) weights for human/vehicle detection only

Question

I am making use of tensorflow's pretrained weights from Tensorflow detection model zoo , which is primarily trained on COCO datasets, which covers about 80 different classes including humans, so making use of these models certainly results in higher computational trade-off, so is there any publicly open pre-trained weights which only focuses on one class in this case either human or vehicle(car).

If there is no such models available then how it is possible to fine-tune or customize these existing models like,

" ssd_inception_v2_coco_2018_01_28 ", which performs pretty well with mAP of 32 and computationally efficient as well , so how such models can be utilized to detect only humans but not any other objects.

Answer 1

Have you tried the model person-vehicle-bike-detection-crossroad-1016 ?
