Types

type Processor

type Processor struct {

	ExternalFramegenTool   string                 // Program to use for frame generation
	ExternalComparisonTool string                 // Program to use for image comparison
	ClusteringMethod       match.ClusteringMethod // Clustering method
	OutputWriter           *bufio.Writer          // where to write the report (nil means stdout)
	SimilarityThreshold    float32                // images with match score above the threshold are considered a match

	ScorePrefix          string // Prefix to use for score records
	UseAbsolutePaths     bool   // When true filenames will be stored in the state with absolute paths
	IgnoreFalsePositives bool   // Treat false positives as matches
	CompactState         bool   // Whether to compact state after processing
	DebugMode            bool   // Enable debug mode

	ChrTolerance  float64 // Luma and Chrominance tolerance
	PropTolerance float64 // proportion tolerance
	// contains filtered or unexported fields
