This article is about how to use OpenCV to load images and display them on the screen. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Picture_display.cpp:

# include

# include

# include

# include

Int main (int argc, char * * argv)

{

IplImage* img = cvLoadImage (argv [1])

CvNamedWindow ("Rayeager PX2", CV_WINDOW_AUTOSIZE)

CvShowImage ("Rayeager PX2", img)

CvWaitKey (0)

CvReleaseImage & img)

CvDestroyWindow ("Rayeager PX2")

}

Makefile:

INCLUDE = $(shell pkg-config-- cflags opencv)

LIBS = $(shell pkg-config-- libs opencv)

SOURCES = picture_display.cpp

# Target file

OBJECTS = $(SOURCES:.cpp=.o)

# executable file

TARGET = picture_display

(TARGET): $(OBJECTS)

Gmail +-o $(TARGET) $(OBJECTS)-I $(INCLUDE) $(LIBS)

(OBJECTS): $(SOURCES)

Gmail +-c $(SOURCES)

Clean:

Rm $(OBJECTS) $(TARGET)

# compilation rule $@ represents the target file $< represents the first dependent file

%. O:%.cpp

Gmail +-I $(INCLUDE)-o $@-c $
