Detailed Description

Main engine class for processing images and applying visual features.

The EngineBase class handles initialization, image processing, and adding a watermark (signo) to images. It utilizes resources for face detection, face mesh, and visual enhancements, such as makeup templates.

Member Function Documentation

addSigno()

void EngineBase::addSigno

(

cv::Mat &

image

)

Adds a watermark (signo) to the specified image.

This method places a copyright text on the bottom right corner of the image.

Parameters

image

Reference to the image (cv::Mat) where the watermark is added.

drawHistoryChart()

void EngineBase::drawHistoryChart	(	cv::Mat &	frame,
		const cv::Rect &	haloRect,
		const std::deque< std::map< std::string, double >> &	history,
		const std::map< std::string, cv::Scalar > &	colors
	)

Draw a simple line chart visualizing the value history for a detection.

Parameters

frame	Image onto which the chart should be drawn.
haloRect	Reference face rectangle used for positioning the chart.
history	Deque containing maps of label->value pairs.
colors	Color mapping for the different labels.

Here is the caller graph for this function:

init()

void EngineBase::init ( std::string  resourcePath )

virtual

Initializes the engine with the specified resource path.

Parameters

resourcePath

Path to the resources needed for initialization.

Reimplemented in SpoofEngine.

Here is the caller graph for this function:

postProcessImage()

cv::Mat EngineBase::postProcessImage ( cv::Mat &  image, cv::Mat &  workingFrame  )

protected

Remove padding and convert the processed image back to the original format.

Parameters

image	Original input image.
workingFrame	Processed frame with padding.

Returns

Final output image.

Here is the caller graph for this function:

preProcessImage()

cv::Mat EngineBase::preProcessImage ( cv::Mat &  image )

protected

Prepare the input image for further processing.

Converts color formats when needed and applies padding around the original image.

Parameters

image

Input image to preprocess.

Returns

Preprocessed frame.

Here is the caller graph for this function:

process()

virtual void EngineBase::process ( cv::Mat &  input, cv::Mat &  output  )

pure virtual

Processes an input image and produces an output image.

This method applies various transformations or effects to the input image using face detection and enhancement tools.

Parameters

input	Reference to the input image (cv::Mat) to be processed.
output	Reference to the output image (cv::Mat) where the result is stored.

Implemented in SpoofEngine.
