Multi-Block LBP is used to encode the rectangular region’s intensity by using local binary patterns. Local Binary Pattern (LBP) looks at nine pixels at a time (i.e., 3x3 window of image = 9-pixel values and 2^9 = 512 possible values). By using Local Binary Pattern we can turn this 3x3 matrix into a single value. LBP focus on the very local neighborhood like 3x3. Multi-block LBP has been used for larger-scale structure. With the help of Multi-Block Local Binary Pattern (MB-LBP), 256 types of different binary patterns can be formed for edge detection and face detection from still images. The computation of the local binary pattern on the 3x3 matrix is shown in Figure. I used MB-LBP For Face Detection.

The best algorithms for face detection in Matlab = Viola-Jones Algorithm Face from the different digital images can be detected. The vision. CascadeObjectDetector uses the Viola-Jones algorithm to detect people’s Faces, Noses, Eyes, Mouth or upper body. The Cascade Object Detector build into MATLAB to detect the facial features from a digital image. Detects the left and right eyes separately. Detects the mouth. Detect the objects using the viola jones algorithm. Detect a pair of eyes. Detects faces that are upright and forward-facing. For Face detection: faceDetector=vision.CascadeObjectDetector('FrontalFaceCART'); For Eyes detection: faceDetector=vision.CascadeObjectDetector('EyePairBig’); I Created a Face Detection system using Viola- Jones algorithm.

Object detection is a computer vision technique for locating instances of objects in images or videos. We can recognize and locate objects of interest within a matter of moments. The goal of object detection is to replicate this intelligence using a computer. For example: in this video, I detected faces from books, newspapers, statues, soft toys using the webcam.

disp ( X )  displays the value of variable X without printing the variable name. And  fprintf  Matlab function allows you to "write" information to the screen for the user to view. For example, here we display the maximum value of S using  disp  function. Here, in this video we used disp function to disply the minimum and maimum values of variable R and S. We also performed different arithmetic operations (+,-,*,/) in the MATLAB command window. What is the difference between disp and fprintf in MATLAB? For Video Click Here...

Face Detection Systems are used for the identification of a person from digital images. The face detection system can extract the different facial features from a digital image. A set of facial features extracted from a digital image includes eyes, nose, mouth and face region. Face recognition is a difficult task due to the different facial expressions. With the help of a face detection system presence of a human face can be detected easily. For the detection of different facial features, the Viola-Jones algorithm is used in the proposed work. To make the task more manageable, Viola-Jones requires full view frontal upright faces. Watch Video:    Nose Detection Facial FEATURES: In any recognition system, the selection of feature extraction plays a vital role. There are a lot of feature extraction techniques proposed efficiency of the proposed system is not acceptable due to the lack of appropriate feature selection. MATLAB CODE: -

Coronavirus  Coronavirus disease 2019 (COVID-19) is a new disease. This virus is a major problem. Coronaviruses are named for the crown-like spikes on their surface. Coronavirus disease (COVID-19) is an infectious disease caused by a new virus. The disease causes respiratory illness (like the flu) with symptoms such as a cough, fever, and in more severe cases, difficulty breathing.  What is Coronavirus?                            Coronaviruses (CoV) are a large family of viruses. How does the Virus works?   viruses work by getting inside the cells your body is made of and then hijacking them. How Do Coronavirus works?        It first infects the cells lining your throat, airways, and lungs and turns them into coronavirus factories.  Different Types of Cells in the Human Body include. Stem cell, bone cell, blood cell, skin cell, muscle cell, sex cell, cancer cell, nerve cell, and fat cell. Protection from Coronavirus.- Take steps to protect yourself Cove
