Hi, examples are available here: https://github.com/SciSharp/SciSharp-Stack-Examples/tree/master/src%2FTensorFlowNET.Examples%2FObjectDetection

The examples use SharpCV. If you want to use opencv sharp it may need 1-2 weeks. Opencv Adapter is under development, which allows you to use opencv sharp with tf.net. You can also use it now by compiling it yourself: https://github.com/SciSharp/OpencvAdapter

Hi,

Thank you for your feedback, concerning the first example, I have an error on the model input image

and when i cast var image_tensors = tf.cast(tn, tf.float32);

another error persists image

Thanks

This is an example with tf v1. You can try to checkout the example repo to branch "tf-align-v1". If the problem still appears, @Oceania2018 is more familiar with tf v1 examples to help you. Or I'll give you a further feed back the day aftet tomorrow since I'm on vacation now and it's not convenient for me to debug it. :)
