What are the model configuration parameters in tensorflow object detection API?

Question

In the Config file there are some parameters which I don't understand properly . I will mention them here.

first_stage_features_stride - Is this the ration of input/output ?

height_stride (In the first_stage_anchor_generator) - What is this ?

Answer 1

First stage feature stride is describing what is the output stride .

So you have to understand what is the difference between input and output strides . Please go with this answer .

Then height stride is the same , Which describe how an anchor should behave in the real image w.r.t the final feature-map .
