It differs from the above function only in what argument(s) it accepts. This is an overloaded member function, provided for convenience. VideoWriter ( const cv :: String & filename, int fourcc, double fps, cv :: Size frameSize, bool isColor = true ) See implementation of “void ColorMap::operator()(InputArray _src, OutputArray _dst) const” in ĭefault constructors. Then the parenthesis operator allows to apply it on an input image. The colormap look-up-table is created only once, when the class is constructed. Wrapper around cv::appl圜olorMap to avoid reallocating memory for the colormap at each call. The color associated to the given palette and name class Metavision :: CvColorMap
Gets a color given a palette and the color name. The color associated to the given palette and type inline const RGBColor & Metavision :: getColor ( const ColorPalette & palette, const std :: string & name ) Gets a color given a palette and the color type. Inline const RGBColor & Metavision :: getColor ( const ColorPalette & palette, const ColorType & type ) HSVColor the color converted in HSV colorspace enum class Metavision :: ColorPalette Įnum class representing available color palettes.Įnum class representing one of the possible type of colors. Utility function to convert from RGB to HSV colorspace. RGBColor the color converted in RGB colorspace inline HSVColor Metavision :: rgb2hsv ( RGBColor rgb ) Utility function to convert from HSV to RGB colorspace. Struct that represents a color in RGB colorspace.Ī fraction between 0 and 1 inline RGBColor Metavision :: hsv2rgb ( HSVColor hsv ) Return false if the thread had not been previously started void reset ( ) True if the thread has been stopped successfully, false otherwise. Also returns false, if the thread is already started. True if the thread started successfully, false otherwise. This means that you don’t need to make a deep copy of it, if you only intend to use the frame until the next one is made available by the callback. The frame passed as a parameter is guaranteed to be available and left untouched until the next time the callback is called. It takes in input the time (in us) of the new frame and the frame. bool start ( std :: uint16_t fps, const PeriodicFrameGenerationAlgorithm :: OutputCb & cb ) Ĭb – Function to call every time a new frame is available. Parametersĭisplay_accumulation_time_us – The time interval to display events from up to now (in us). The events shown at each refresh are such that their timestamps are in the last ‘display_accumulation_time_us’ microseconds from the last received event timestamp.
Sets the time interval to display events. Void set_display_accumulation_time_us ( timestamp display_accumulation_time_us ) Parametersīegin – Beginning of the buffer of events Palette – The Prophesee’s color palette to use void add_events ( const Metavision :: EventCD * begin, const Metavision :: EventCD * end ) Īdds the buffer of events to be displayed. Sets the color used to generate the frame. Void set_color_palette ( const Metavision :: ColorPalette & palette ) Off_color – Color used for off events, default: black cv:Scalar::all(0)Ĭolored – If the generated frame should be single or three channels On_color – Color used for on events, default: white cv::Scalar::all(255)
Parametersīackground_color – Color used as background, when no events were received for a pixel, default: grey cv::Scalar::all(128) If the parameter colored is true, then the generated frame will be 8 bits three channels. If the parameter colored is false, then the generated frame will be 8 bits single channel and the first channel will be used to define each colors (i.e. Sets the color used to generate the frame.īy default, the frame generated will be 8 bits single channel with the default colors grey, white, black as background, on and off colors respectively. void set_colors ( const cv :: Scalar & background_color, const cv :: Scalar & on_color, const cv :: Scalar & off_color, bool colored = false ) Note that if true it can slow down the process.ĭestructor. Process_all_frames – If true, it will process all frames, not just the latest one. Public Functions CDFrameGenerator ( long width, long height, bool process_all_frames = false )
