fernandoc1 / extract_roi.cpp
Created September 24, 2019 21:53
This extracts a ROI from images that are 16bits per pixel.
void extractRoi(cv::Mat& inImage, cv::Mat& outImage, cv::Rect roi)
{
/* Create the image */
outImage = cv::Mat(roi.height, roi.width, inImage.type());
/* Populate the image */
for (int i = roi.y; i < (roi.y+roi.height); i++)
{
uint16_t* inP = inImage.ptr<uint16_t>(i);
uint16_t* outP = outImage.ptr<uint16_t>(i-roi.y);

Training TensorFlow models in C

Training TensorFlow models in C

Python is the primary language in which TensorFlow models are typically developed and trained. TensorFlow does have bindings for other programming languages. These bindings have the low-level primitives that are required to build a more complete API, however, lack much of the higher-level API richness of the Python bindings, particularly for defining the model structure.

This gist demonstrates taking a model (a TensorFlow graph) created by a Python program and running the training loop in a C program.
