Semantic Segmentation Model

DeepLobe's Semantic Segmentation model is a powerful tool for understanding the visual content of images at a pixel-level. Unlike Object Detection or Instance Segmentation models that identify and classify objects within an image, Semantic Segmentation goes a step further by assigning a semantic label to each pixel in the image. This allows for a more detailed and fine-grained understanding of the image's content.

The Semantic Segmentation model in DeepLobe is trained to recognize and segment different classes of objects or regions within an image. It can accurately label pixels belonging to classes such as buildings, roads, vegetation, sky, and more. This level of understanding is essential for various applications, including autonomous driving, urban planning, and environmental monitoring.

By leveraging state-of-the-art deep learning techniques, the Semantic Segmentation model analyzes the visual features and patterns present in an image to identify and classify pixels into different semantic classes. This enables users to gain valuable insights into the distribution and composition of different objects or regions within the image.

With DeepLobe's no-code AI platform, you can create custom Semantic Segmentation models tailored to your specific use cases. Whether you need to segment objects in satellite images, analyze medical scans, or extract meaningful information from aerial imagery, DeepLobe provides the tools and capabilities to train and deploy highly accurate Semantic Segmentation models without the need for coding.

Next, we will guide you through the steps and workflow of creating a custom Semantic Segmentation model using DeepLobe's intuitive interface and powerful features.

• DeepLobe will convert the video into a sequence of images based on the chosen frame rate. Please note that these frames/images will not be annotated, so you will need to manually annotate them or hire a professional annotator.

Add Data using JSON files

Additionally, you have the option to upload annotated data in .json format. If you have already annotated your data externally, you can upload the annotations to DeepLobe. This allows you to utilize pre-existing annotations and speed up the training process. To add data using JSON files:

1. Click on the "Upload JSON" button on the project creation screen.
2. Select the JSON file containing the annotations.
3. DeepLobe will use this annotated data to train your Instance Segmentation model.

It's important to have accurate and comprehensive annotations for training your v model effectively. Well-annotated data helps the model learn and identify objects accurately in images or videos.

Annotate Training Data

Annotation for Semantic Segmentation Model: To annotate your dataset for the custom Semantic Segmentation Model in DeepLobe, you can follow a similar annotation process as in the Instance Segmentation model. Here are the steps:

Upload and Prepare Your Dataset

Ensure that you have a minimum of 50 files in your dataset. Once uploaded, click on "Continue" to proceed to the labeling tool. DeepLobe's intuitive annotation tool allows you to manually label objects and annotate your images. Here's how:

• An image from your dataset will be displayed in the labeling tool.
• Draw polygons around the objects or regions of interest in the image. Click on the image to add vertices and create a polygon that accurately outlines the object.
• Assign a label or class to each polygon by clicking on the "Add label" button and entering the appropriate label, such as "person," "car," or any other relevant category. You can assign different labels to different objects in the image.

Review and Edit Annotations

After annotating an image, you can review and edit the annotations as needed. You can adjust the position of the polygons, modify labels, or delete incorrect annotations. It is important to ensure that the annotations accurately represent the objects or regions of interest in the image.

Annotate the Entire Dataset

Repeat the annotation process for each image in your dataset. Take your time to ensure accurate and comprehensive annotations for each object or region of interest. The quality of annotations directly impacts the performance of your Semantic Segmentation model.

Once you have completed annotating all the images in your dataset, the tool automatically saves your annotations for the next steps of training a custom model.

Accurate and detailed annotations are crucial for training your Instance Segmentation model effectively. They help the model learn to identify and segment individual instances of objects within the images accurately.

Data Health Check

In the custom Semantic Segmentation model flow, DeepLobe provides a Data Health Check stage to evaluate the quality and balance of your training and validation data sets. This stage allows you to assess the health of your data and take necessary actions to improve the precision and performance of your models.

DeepLobe offers powerful analysis tools, such as Class Balance, to assist you in identifying potential gaps or imbalances within your data. These tools highlight classes with a minority of data, making it easier for you to identify areas where additional data is needed to improve the model's performance.

To improve the health of your data and enhance the accuracy of your model, consider the following steps:

Add More Data

If the analysis reveals that certain classes have a limited number of samples, it is advisable to add more data for those classes. Collecting additional samples will provide a more diverse and representative training set, enabling the model to learn effectively.

Evenly Distribute Training Data

Ensure that your training data is evenly distributed across different classes. Imbalanced training data, where certain classes have significantly more samples than others, can lead to biased models. By evenly distributing the training data, you create a balanced learning environment that promotes fair and accurate predictions for all classes.

By following these steps, you can improve the quality and health of your data, leading to better model performance and more reliable object detection results.

DeepLobe's Data Health Check stage empowers you to evaluate and optimize your training and validation data sets, ultimately enhancing the effectiveness and accuracy of your custom object detection models.
