Object Detection Technology Unveiled: How It’s Transforming Industries


 In computer vision, object detection identifies and locates objects in images and videos. Object detection technology may sound like a pinnacle in artificial intelligence, but it co-exists with us in our lives. Hiding in plain sight, we often fail to notice simple applications of object detection around us.

Have you ever wondered how a face unlock works on your smartphone or how a self-driving car operates on its own?

The answer is object detection.

What is Object Detection Technology?

Technically object detection is a technology that includes computer vision and image processing. Used to detect objects in images or videos. Sounds interesting? 

Let’s break it down for you using a simple example.  Self-driving cars make use of moving object detection technology where computer vision and image processing are used to determine the distance between the car and the moving objects to create alerts and guide the self-driving cars. Different Car gadgets are used to improve the driver experience.

What is the Technology Behind it? 

What is the Technology Behind it? 

Well, artificial intelligence is the basic principle that drives object detection. The idea is simple. The data is collected through computer vision. The data is then fed into the model using machine learning algorithms or deep learning algorithms, inclusions are made, and the camera collects the image from different angles and sends it to the image processing unit.

Now, based on the training data used to train the model and the trained model, the results are given to the system in the form of alerts or instructional guidelines, like how far the object is. If the object is moving or if the object has stopped.

Top 5 Object Detection Technology Algorithms in Machine Learning

Object detection is one of the problems in computer vision.

1. R-CNN

R-CNN stands for Region-based Convolutional Neural Networks. R-CNN uses the Selective Search method to extract ROI (regions of interest) from the input image.

Regions Of Interest is a rectangle that represents the boundary of an object in the image. There may be many Regions Of Interest in an Image.

Each ROI is passed to a neural network to produce output features. A collection of support-vector machine classifiers is used to determine what type of object is present in the ROI.


So, in R-CNN, the first part is selective search. What that means is to find something from an image. Our job is to get bounding boxes from an input image.

We will find similarities in those pixels in the image based on various factors like similar colors, light, and texture. Nearby pixels are similar in color or texture or like that.

So, that’s how R-CNN works. Here is the full diagram for our CNN input image.

R-CNN Diagram

From the selective source, we got the bounding boxes. Then, these are cropped and passed into a CNN network to predict the class and it predicts bounding boxes. Since these bounding boxes are not accurate…  It’s not accurate because it is got from selective search and it is going to predict the original bounding box, I mean better bounding box from the network, CNN network.

There are a lot of drawbacks on the R-CNN:
The original image was a rectangle and the CNN network takes a fixed-size

The CNN network has to pass these images multiple times.

2. Fast R-CNN

What it does is, the entire image is passed into the deep convolutional network or simply the CNN network. The image is passed into CNN to get a fissure map. Whatever output, we call it a fissure map. The bounding box is projected on the feature map just the way it is on the input image that way It is projected on the feature map. It is called ROI projection, which means a region of interest projection.

And that’s what it is. It will take these values by the ROI pooling layer and then it will make it fixed size. Since the fully connected layer doesn’t work in different sizes, the ROI pooling layer is used to make the ROI projection into a fixed size. Then fully connected network will classify this into objects, what kind of object it is, and also will predict an accurate bounding box.

Since this bounding box was predicted by selective search only. So, that’s it for fast R CNN. 

3. Faster R-CNN

And let’s see what happens on faster R-CNN.  So, it is also the same with the fast R CNN, it has an input image, it passes into the convolutional layer at once, and it has a feature map, just like the fast R-CNN.  However,  the projection on the feature map was from a selective search in the case of fast R-CNN.

But, here, It is not from Selective Search, it is from RPN or  Region Proposal Network. It is much, much faster than the other versions of R-CNN.


So, what exactly RPN is? The feature map is generated from the input image by the Convolutional Network. This fissure map is passed into a convolutional network to predict objectness classification and bounding box.

It predicts the bounding box on the fissure map and also predicts whether the object is present or not. It is not classification, it will not classify what object is in there, it is just going to classify whether this bounding box contains an object or not. So that’s all. So this way, it gives these,  bounding boxes.

4. Mask R-CNN

R-CNN focuses on object detection, but Mask R-CNN also adds instance segmentation features. Mask R-CNN also replaces the ROI Pooling method with a new method called ROI Align.

ROI Align can represent fractions of a pixel.

5. Spatial Pyramid Pooling

The convolutional neural networks require fixed-size input images. However, the new network structure, called Spatial Pyramid Pooling, can generate a fixed-length representation regardless of input image size. Therefore SPP-net is faster than R-CNN algorithms giving comparable accuracy.
