Public Functions
-
inline PriorBox()
Constructor.
-
void Init(const std::vector<int64_t> &min_sizes, const std::vector<int64_t> &max_sizes, const std::vector<float> &aspect_ratios, const std::vector<float> &variances, const int64_t image_size_w, const int64_t image_size_h, const float step_w, const float step_h, const bool clip, const bool flip, const float offset)
Method to init the op’s attributes.
- 参数
min_sizes – [in] Define the minimum side length of square boxes, can be multiple.
max_sizes – [in] Define the maximum side length of square boxes as sqrt(min_size * max_size), can be multiple.
aspect_ratios – [in] Define the aspect ratios of generated boxes. For each aspect_ratio, the width and height are min_size * sqrt(aspect_ratio) and min_size / sqrt(aspect_ratio) respectively.
variances – [in] Define variances for adjusting the prior boxes.
image_size_w – [in] Define the width of the image.
image_size_h – [in] Define the height of the image.
step_w – [in] Define the ratio of the image width and the feature map width.
step_h – [in] Define the ratio of the image height and the feature map height.
clip – [in] Define whether clip the prior boxes to [0.0, 1.0].
flip – [in] Define whether flip aspect ratios. If true, with an aspect ratio r, ratio 1.0/r will be generated.
offset – [in] Define the offset to the zero points of width and height.
