People counting tool

Building a people counting solution could be both—a fun project and one that actually finds real-world applications.

To detect and count people present in an image, you’ll need a relevant training dataset and a data training platform. You can use a free tool like OpenCV to label your data or an auto annotation tool like V7 to complete this project faster.

Since the COVID-19 outbreak, people counting solutions have been growing in popularity, helping to enforce social distancing rules and improve safety.

Here’s a recommended dataset to get you started:

• People Counting Dataset (PCDS)
  

Colors detection

Next up is a simple colors detector that you can use for a wide variety of visual tasks.

From detecting colors to build the green screen app—replacing the green background with a custom video or background—to a simple photo editing software, building a color recognizer is an awesome project to get started with Computer Vision.

Here are a few interesting datasets you might want to use for your project:

• Google-512 dataset
• Lego colors
• Passport colors
  

Object tracking in a video

Next, consider taking on a bit more advanced computer vision task—object tracking in a video. 

Object tracking is about estimating the state of the target object present in the scene from previous information. 

You can build simple object tracking models using videos involving one object, such as a car, or multiple objects like pedestrians, animals, and whatnot. 

Essentially, the model will perform two tasks—predicting the object’s next state and correcting this state with respect to the object’s real condition. Object tracking models find applications in traffic control and human-computer interactions.

Here are a few video datasets you might find interesting for this computer vision task:

• TLP Datasets
• Tracking Net
• MOT17

Pedestrian detection

Building an object detection model to detect pedestrians is one of the simplest and fastest computer vision projects to complete.

All you need is a relevant dataset of high-quality images and a data training platform to train and test your model. You can use one of the free image annotation tools or try out V7.

Pedestrian detectors are commonly used in the automotive industry for traffic safety as well as human-robot interactions and intelligent video systems.

Consider these datasets to get started:

• Caltech Pedestrian Dataset 
• Penn-Fudan Database for Pedestrian Detection
• Pedestrian Detection Dataset (Kaggle)
  

Hand gesture recognition

Hand gesture recognition is a bit more advanced computer vision task requiring you to firstly separate the hand region from the background and then to segment the fingers to predict hand gestures.

You can use OpenCV if you want to keep your model simple or take advantage of V7’s keypoint skeleton & custom polygons tools to make labeling faster and more accurate.

After training, you can test your model using a webcam. Hand gesture models can be used in VR games and sign languages.

Check out those datasets to get started:

• Hand Gestures of digits from 0 to 5
• Hand Gesture Recognition Database
• Multi-Modal Hand Gesture Dataset

Human emotion recognition

If you decide to go with a bit more challenging task, consider building an emotion detection model. You can base your model on six main facial emotions: happiness, sadness, anger, fear, disgust, and surprise.

The three main components of this project include Image Pre-processing, Feature Extraction, and Feature Classification. 

Here are the datasets that might come in handy:

• AffectNet
• FER-2013
  

Road lane detection

Road lane detection is yet another computer vision model that plays a key role in the development of the automotive industry.

Used primarily for self-driving cars, a road lane detector can be a fun beginner project that will help you get hands-on experience with both images and videos.

Here is a couple of datasets to help you out:

• CULane Dataset
• KITTI-Road/Lane Detection Evaluation 2013
  

Business card scanner

Developing a business card scanner can be done using the OCR (Optical Character Recognition) technology. Your trained model will find and extract information from business cards.

Essentially, this project will be divided into three phases: image processing (noise cancellation), OCR (text extraction), and classification (classifying key properties).

You can use your business card reader to automate data entry.

Pick on one of those datasets to begin:

• Stanford Mobile Visual Search Data Set: Business Cards
• Indian Business Cards Sample Images
  

💡 Pro Tip: V7 allows you to automatically scan and read text using in-built Text Scanner.

License plate recognition

A license plate recognizer is another idea for a computer vision project using OCR.

However, there are two challenges related to this project: data collection and the differences in license plates formats depending on the location/country.

Therefore, your model might not be accurate unless you train large amounts of data (if you manage to obtain it).

Note: License plate numbers are considered sensitive data, so make sure you stick to the publicly available datasets when building your models.

A simple automatic license plate recognition system can use basic image processing techniques, and you can build it using OpenCV and Python. 

However, more advanced systems use object detectors like YOLO or Fast C-RNN.

Automatic license plate recognition can be used for security, parking, smart cities, automatic toll collection, and access control.

Here are a few datasets you might consider:

• Car License Plate Detection
• UCSD Car Dataset
• Vehicles License Plates
  

Handwritten digit recognition

This project is a perfect start for computer vision newbies—you can build a simple digit recognizer using the MNIST dataset. 

As you get a chance to train your model using Convolutional Neural Networks, you’ll learn how to develop, evaluate, and use convolutional deep learning neural networks for image classification.

The MNIST dataset contains a training set of 60,000 examples and a test set of 10,000 examples. You can access it here:

• MNIST Digit Recognition Dataset

Iris Flowers Classification 

Here’s another computer vision project based on one of the most popular and thus readily available datasets for pattern recognition—Iris Flowers Classification Dataset.

It contains three classes of 50 instances each, where each class refers to a type of iris plant. 

It’s a great beginner’s project that’ll help you get hands-on experience with image classification as you’ll train your model to predict the species of a new iris flower.

You can download the dataset here:

• Iris Flowers Classification Dataset
