Step 3: Apply a perspective transform to obtain the top-down view of the document.ĭriver drowsiness detection is a car safety technology which helps prevent accidents caused by the driver getting drowsy. Step 2: Use the edges in the image to find the contour (outline) representing the piece of paper being scanned. Document Scannerīuilding a document scanner with OpenCV can be accomplished in just three simple steps: Law enforcement may also use mobile devices to identify people during police stops. Face recognition systems can be used to identify people in photos, video, or in real-time. In the closed eye, the vertical line almost disappears.įace recognition is a method of identifying or verifying the identity of an individual using their face. The size of the horizontal line is almost identical in the closed eye and in the open eye while the vertical line is much longer in the open eye in coparison with the closed eye. We first detect the eyes & then, we detect two lines: an horizontal line and a vertical line crossing the eye. Eye Blink Detectionĭetect if an eye blink or not. It can used in Face part extraction (i.e., nose, eyes, mouth, jawline, etc.), Facial alignment, Head pose estimation, Face swapping, Blink detection …and much more applications! 9. Apply the shape predictor, specifically a facial landmark detector, to obtain the (x, y)-coordinates of the face regions in the face ROI. This can be accomplished using a number of different techniques, but normally involve either Haar cascades or HOG + Linear SVM detectors. I have used pre-trained HOG + Linear SVM object detector specifically for the task of face detection.ĭownload shape_predictor_68_face_landmarks.dat from here:-ĭetecting facial landmarks in an image is a two step process:įirst i have localize a face(s) in an image. Facial Landmark Detectionĭetect all landmarks of face like Eyes, Nose, Lips, Eyebrows. Number Plate Detectionĭetecting Number plate from image (or webcam) of cars. #Cvmini code
This code helps you track an object-of-interest to draw colored lines on the screen (just like the Paint application but using the webcam).
Multiple color detection is used in some industrial robots, to performing pick-and-place task in separating different colored objects. In self-driving car, to detect the traffic signals. 
Color detection is necessary to recognize objects, it is also used as a tool in various image editing and drawing apps. Color DetectionĬolor detection is the process of detecting the name of any color. It can be used in a face recognition app to improve accuracy. Simple python program to extract faces from an image. Live SketchĬonvert an image or a video into a sketch. It can be used to apply different types of color filters. Used one image color (source) to change the color of different image (target) using both Color Transfer Algorithm as well as color_transfer modules. Can increase or decrease blur strength by changing the kernel. It can be used for Privacy & Identity Protection in public/private areas. Use GaussianBlur with a kernel of (91,91) to blur faces. Here are some projects & their applications which can be build using openCV:- 1.

The library is cross-platform and free for use under the open-source BSD license. Originally developed by Intel, it was later supported by Willow Garage then Itseez. OpenCV (Open Source Computer Vision Library) is a library of programming functions mainly aimed at real-time computer vision.
Using digital images from cameras and videos and deep learning models, machines can accurately identify and classify objects - and then react to what they “see.” Computer vision is a field of artificial intelligence that trains computers to interpret and understand the visual world.
