Types

type Bin 

type Bin struct {
	UpperBound float64
	Label      string
}

Bin stores the thresholds that turns counts into labels

func NewThresholds 

func NewThresholds(t map[string]int) []Bin

NewThresholds creates a list of thresholds for labeling counts

type BoundingBox 

type BoundingBox struct {
	// contains filtered or unexported fields
}

func NewBoundingBox 

func NewBoundingBox(coords BoundingBoxConfig) (BoundingBox, error)

func (BoundingBox) Crop 

func (bb BoundingBox) Crop(img image.Image) image.Image

crop coordinates were already validated upon configuration empty bounding box implies no crop

type BoundingBoxConfig 

type BoundingBoxConfig struct {
	XMin float64 `json:"x_min"`
	XMax float64 `json:"x_max"`
	YMin float64 `json:"y_min"`
	YMax float64 `json:"y_max"`
}

type Config 

type Config struct {
	DetectorName    string                         `json:"detector_name"`
	ChosenLabels    map[string]float64             `json:"chosen_labels"`
	CountThresholds map[string]int                 `json:"count_thresholds"`
	CountPeriod     float64                        `json:"sampling_period_s"`
	NSamples        int                            `json:"n_samples"`
	ExtraFields     map[string]interface{}         `json:"extra_fields"`
	ValidRegions    map[string][]BoundingBoxConfig `json:"valid_regions"`
}

Config contains names for necessary resources

func (*Config) Validate 

func (cfg *Config) Validate(path string) ([]string, []string, error)

Validate validates the config and returns implicit dependencies, this Validate checks if the camera and detector exist for the module's vision model.

type RingBuffer 

type RingBuffer struct {
	// contains filtered or unexported fields
}

func NewRingBuffer 

func NewRingBuffer(size int) *RingBuffer

func (*RingBuffer) Add 

func (rb *RingBuffer) Add(newCount float64)

func (*RingBuffer) Len 

func (rb *RingBuffer) Len() int

func (*RingBuffer) Mean 

func (rb *RingBuffer) Mean() float64

func (*RingBuffer) MeanLabel 

func (rb *RingBuffer) MeanLabel(thresholds []Bin) string

func (*RingBuffer) ModeLabel 

func (rb *RingBuffer) ModeLabel(thresholds []Bin) string

func (*RingBuffer) String 

func (rb *RingBuffer) String() string
