As LBP is a visual descriptor it can also be used for face recognition tasks, as can be seen in the following step-by-step explanation. Steps of the algorithm: Parameters: the LBPH uses 4 parameters: Radius: the radius is used to build the circular local binary pattern and represents the radius around the central pixel. ItContinue reading “LBPH Algorithm”

Twilio is a cloud based Platform-as-a-Service platform. Twilio allows software developers to programmatically make and receive phone calls, send and receive text messages using its web service APIs. Services provided by Twilio: 1.Allows to make calls from apps to landline and mobile devices. 2.Real time video collaboration infrastructure provides video collaboration and context sharing intoContinue reading “TWILIO API”

we are using a PIR motion sensor. PIR stands for passive infrared. This motion sensor consists of a fresnel lens, an infrared detector, and supporting detection circuitry. The lens on the sensor focuses any infrared radiation present around it toward the infrared detector. Our bodies generate infrared heat, and as a result, this heat isContinue reading “Integrating PIR Sensor with Raspberry pi(17/4/2020)”

A SMS API is well-defined software interface which enables code to send short messages via a SMS Gateway. As the infrastructures for SMS communications and the internet are mostly divided, SMS APIs are often used to ‘bridge the gap’ between telecommunications carrier networks and the wider web.  SMS APIs are used to allow web applications to easily send and receiveContinue reading “SMS Module using Twilio API(10/4/2020)”

PIR sensors are more complicated than many of the other sensors explained in these tutorials (like photocells, FSRs and tilt switches) because there are multiple variables that affect the sensors input and output. The IR sensor itself is housed in a hermetically sealed metal can to improve noise/temperature/humidity immunity. There is a window made ofContinue reading “PIR SENSORS(3/4/2020)”

Raspberry Pi is the name of a series of single-board computers made by the Raspberry Pi Foundation, a UK charity that aims to educate people in computing and create easier access to computing education. The Raspberry Pi launched in 2012, and there have been several iterations and variations released since then. The original Pi had aContinue reading “Raspberry Pi(27/3/2020)”

Haar Cascade is a machine learning object detection algorithm. It is a machine learning based approach where a cascade function  is trained from a lot of positive and negative images (where positive images are those where the object to be detected is present, negative are those where it is not).It is then used to detect objects inContinue reading “Face recognition with OpenCV: Haar Cascade(20/3/2020)”

Introduction Learn how to connect the Raspberry Pi Camera Module to your Raspberry Pi and take pictures, record video, and apply image effects. There are two versions of the Camera Module: The standard version, which is designed to take pictures in normal light The NoIR version, which doesn’t have an infrared filter, so you canContinue reading “Getting started with the Camera Module”

This Project proposes the smart surveillance system using Raspberry Pi and PIR sensor. This system will serve as the smart security module for monitoring. Raspberry Pi camera module is used to capture images once the motion is detected by the PIR sensor and it checks for images that are already uploaded in the database andContinue reading “INTRODUCTION”
