Stacks multiple images into a single, all focused image. The input images need to be aligned and in order. The function also returns a depth_info image that contains the information against each pixel where it was picked from the stack.
Function
CUVI_EXPORTS CuviStatus focusStack(CuviImage* images, const int numImages, CuviImage& stack, CuviImage& depth_info, const CuviFilter denoiseFilter, const CuviStream& stream);

Code Example
std::string path = "D:/dataset/fs/imageFolder/";
std::string result = "D:/dataset/fs/focused.png";
for (const auto& entry : fs::directory_iterator(path))
{
if (entry.path().has_extension() && isSupportedExtension(entry.path().extension().string()))
vec.push_back(entry.path().string());
}
int numImages = vec.size();
vector<CuviImage> ImgArr(numImages);
//Sort filesnames to read in order. THIS IS VERY IMPORTANT FOR FOCUS STACKING
sort(vec.begin(), vec.end(), lessFirst);
for (int i = 0; i < numImages; i++)
{
ImgArr[i].create(vec[i], CUVI_LOAD_IMAGE_COLOR_KEEP_DEPTH);
cout << vec[i]<< std::endl;
}
CuviImage focusImage, slice_info;
CuviFilter denoiseFilter = CuviSpecialFilters::gaussian(CuviSize(11, 11), 15.0f);
cuvi::computerVision::focusStack(ImgArr.data(), numImages, focusImage, slice_info, denoiseFilter);
printf("\nSaving to disk..");
cuvi::io::saveImage(focusImage, result);
