Struct ObjectDetectionAveragePrecisionParams

pub struct ObjectDetectionAveragePrecisionParams {
    pub num_classes: Option<i32>,
    pub iou_thresholds: Vec<f32>,
    pub num_recall_points: Option<i32>,
}

Parameters that define how Average Precision is computed for Object Detection task. Refer for details: http://cocodataset.org/#detection-eval

Next ID: 4

Fields

num_classes: Option<i32>

Total object classes. The AP value returned for each IoU threshold is an average over all classes encountered in predicted/ground truth sets.

iou_thresholds: Vec<f32>

A predicted box matches a ground truth box if and only if IoU between these two are larger than an IoU threshold. AP is computed for all relevant {IoU threshold, class} combinations and averaged to get mAP. If left empty, evaluation is done for all IoU threshods in the range 0.5:0.05:0.95 (min:increment:max).

num_recall_points: Option<i32>

AP is computed as the average of maximum precision at (1

• num_recall_points) recall levels. E.g., if num_recall_points is 10, recall levels are 0., 0.1, 0.2, …, 0.9, 1.0. Default: 100

Implementations

impl ObjectDetectionAveragePrecisionParams

pub fn num_classes(&self) -> i32

Returns the value of num_classes, or the default value if num_classes is unset.

pub fn num_recall_points(&self) -> i32

Returns the value of num_recall_points, or the default value if num_recall_points is unset.

Trait Implementations

impl Clone for ObjectDetectionAveragePrecisionParams

fn clone(&self) -> ObjectDetectionAveragePrecisionParams

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ObjectDetectionAveragePrecisionParams

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ObjectDetectionAveragePrecisionParams

fn default() -> Self

Returns the “default value” for a type.

impl Message for ObjectDetectionAveragePrecisionParams

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message to a buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for ObjectDetectionAveragePrecisionParams

fn eq(&self, other: &ObjectDetectionAveragePrecisionParams) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
