Matting Result
The MattingResult code is defined in fastdeploy/vision/common/result.h, and is used to indicate the predicted value of alpha transparency predicted and the predicted foreground, etc.
C++ Definition
``fastdeploy::vision::MattingResult`''
struct MattingResult {
std::vector<float> alpha;
std::vector<float> foreground;
std::vector<int64_t> shape;
bool contain_foreground = false;
void Clear();
std::string Str();
};
- alpha: It is a one-dimensional vector, indicating the predicted value of alpha transparency. The value range is [0.,1.], and the length is hxw, in which h,w represent the height and the width of the input image seperately.
- foreground: It is a one-dimensional vector, indicating the predicted foreground. The value range is [0.,255.], and the length is hxwxc, in which h,w represent the height and the width of the input image, and c is generally 3. This vector is valid only when the model itself predicts the foreground.
- contain_foreground: Used to indicate whether the result contains foreground.
- shape: Used to indicate the shape of the output. When contain_foreground is false, the shape only contains (h,w), while when contain_foreground is true, the shape contains (h,w,c), in which c is generally 3.
- Clear(): Member function used to clear the results stored in the structure.
- Str(): Member function used to output the information in the structure as string (for Debug).
Python Definition
fastdeploy.vision.MattingResult
- alpha(list of float): It is a one-dimensional vector, indicating the predicted value of alpha transparency. The value range is [0.,1.], and the length is hxw, in which h,w represent the height and the width of the input image seperately.
- foreground(list of float): It is a one-dimensional vector, indicating the predicted foreground. The value range is [0.,255.], and the length is hxwxc, in which h,w represent the height and the width of the input image, and c is generally 3. This vector is valid only when the model itself predicts the foreground.
- contain_foreground(bool): Used to indicate whether the result contains foreground.
- shape(list of int): Used to indicate the shape of the output. When contain_foreground is false, the shape only contains (h,w), while when contain_foreground is true, the shape contains (h,w,c), in which c is generally 3.
