Detailed Description

Class Substracter Extracts an object over an image given a filled image and an empty image.

Filled image stands for scene image with object in and empty image stands for image of the scene without the object. It uses standard opencv morphological operators to compute a black and white mask that is then applied on the filled image to extract the object. It handles also object image storage.

Member Function Documentation

void jafar::cutter::Substracter::extractObjectOnImage	(	const JfrImage_TypeColorSpace &	cs,
		const float &	threshold = 250
	)

extracts the object from the scene applying a a good value is in [250 254].

Besides the computed image is converted to color space

jafar::image::Image jafar::cutter::Substracter::getMaskImg

(

)

Returns:

computed binary mask image

jafar::image::Image jafar::cutter::Substracter::getObjectImg

(

)

Returns:

the image of the object

bool jafar::cutter::Substracter::loadEmptyImg

(

const char *

fileName

)

loads the empty scene image from a file

Returns:

whether the loading was a success or not

bool jafar::cutter::Substracter::loadFilledImg

(

const char *

fileName

)

loads the image of the scene with object[s] from a file

Returns:

whether the loading was a success or not
