Normalize(const std::vector<float> &mean, const std::vector<float> &std)
Constructor.
- Parameters
mean – [in] A vector of mean values for each channel, with respect to channel order. The mean values must be in range [0.0, 255.0].
std – [in] A vector of standard deviations for each channel, with respect to channel order. The standard deviation values must be in range (0.0, 255.0].
Example/* Define operations */ auto decode_op = vision::Decode(); auto normalize_op = vision::Normalize({128, 128, 128}, {1.0, 1.0, 1.0}); /* dataset is an instance of Dataset object */ dataset = dataset->Map({decode_op, normalize_op}, // operations {"image"}); // input columns
