How to train a Detecto model on a custom dataset?

You’ll be glad to know that training a Detecto model on a custom dataset is just as easy; again, all you need is 5 lines of code, as well as either an existing dataset or some time spent labeling images. In this tutorial, we’ll start from scratch by building our own dataset.

Can I use the library for object detection?

Using the library can be tricky for beginners and requires the careful preparation of the dataset, although it allows fast training via transfer learning with top performing models trained on challenging object detection tasks, such as MS COCO.

How do I fit a model on the training dataset?

Next, the model can be fit on the training dataset by calling the train () function and passing in both the training dataset and the validation dataset. We can also specify the learning rate as the default learning rate in the configuration (0.001). We can also specify what layers to train.

Can imported Detecto detect custom objects?

Imported Detecto’s modules Generated the top predictions on our image Detecto uses a Faster R-CNN ResNet-50 FPN from PyTorch’s model zoo, which is able to detect about 80 different objects such as animals, vehicles, kitchen appliances, etc. However, what if you wanted to detect custom objects, like Coke vs. Pepsi cans, or zebras vs. giraffes?

How do you learn object detection?

1. A Simple Way of Solving an Object Detection Task (using Deep Learning)First, we take an image as input:Then we divide the image into various regions:We will then consider each region as a separate image.Pass all these regions (images) to the CNN and classify them into various classes.More items...•

How many images are needed to train an object detection?

For each label you must have at least 10 images, each with at least one annotation (bounding box and the label). However, for model training purposes it's recommended you use about 1000 annotations per label. In general, the more images per label you have the better your model will perform.

What is the best object detection model?

The best real-time object detection algorithm (Accuracy) On the MS COCO dataset and based on the Mean Average Precision (MAP), the best real-time object detection algorithm in 2021 is YOLOR (MAP 56.1). The algorithm is closely followed by YOLOv4 (MAP 55.4) and EfficientDet (MAP 55.1).

What type of learning and machine learning techniques are used for object detection?

Object detection can be done by a machine learning approach and a deep learning approach. The machine learning approach requires the features to be defined by using various methods and then using any technique such as Support Vector Machines (SVMs) to do the classification.

How much data do I need for object detection?

The minimum number of image data for training is around 150–500.

How many pictures do you need to train YOLOv5?

To achieve a robust YOLOv5 model, it is recommended to train with over 1500 images per class, and more then 10,000 instances per class. It is also recommended to add up to 10% background images, to reduce false-positives errors.

Is object detection deep learning?

Object detection is a computer vision technique for locating instances of objects in images or videos. Object detection algorithms typically leverage machine learning or deep learning to produce meaningful results.

Train a custom object detection model in less than 5 min

While it’s quite simple to launch object detection from pre-trained models, things may become harder when training your custom object detection model. This post describes how this task is efficiently tackled in few clicks with Ikomia platform.

Conclusion

I hope you will enjoy the simplicity of Ikomia Studio. No more time wasted to train custom object detection model such as YOLO. You may find other interesting algorithms in the Marketplace. So feel free to have a look and discover them.

First step is setting up the environment

For running the object detection model on your system, you must fulfill the necessary requirements of setting up the environment. You must install a Tensorflow-GPU and an Anaconda virtual environment with Python 3.6. We recommend to install an NVIDIA GPU.

Second step is to prepare the faster RCNN Model

The most important step for training a model with custom images is to prepare the Tf -records

Third step is to configuring the Training Pipeline

The training pipeline is required to organize and automate hyperparameter tuning, pre-processing, model training, and post-processing tasks. It defines which models and what parameters will be used for training and points through the training images and data. For this purpose, We have used the faster_rcnn_inceptionv2_pets.config file.
