Deeplabv3 Mobilevit X Small
Ever wondered how some AI models can efficiently process images? Meet the Deeplabv3 Mobilevit X Small model, a unique combination of MobileViT and DeepLabV3. This model is designed to be lightweight and fast, making it perfect for mobile devices. But what makes it special? It uses a new block that replaces local processing in convolutions with global processing using transformers, allowing it to process images quickly and accurately. With its ability to perform semantic segmentation, this model can identify objects in images with ease. Plus, it's been pre-trained on ImageNet-1k and fine-tuned on PASCAL VOC2012, making it a reliable choice for various tasks. So, how does it work? Simply put, it converts image data into flattened patches, processes them using transformers, and then 'unflattens' them back into feature maps. This allows the model to be placed anywhere inside a CNN, making it a versatile tool for image processing.

Limitations
Current Model is a powerful tool for semantic segmentation, but it’s not perfect. Let’s talk about some of its limitations.
- Limited Resolution: The model is trained on images with a resolution of 512x512 pixels.
- Preprocessing Requirements: The model expects images to be in BGR pixel order, not RGB.
- Limited Training Data: The model was pretrained on ImageNet-1k, a dataset with 1 million images and 1,000 classes.
Format
MobileViT + DeepLabV3 is a special type of computer vision model that combines the strengths of two different models: MobileViT and DeepLabV3. This model is designed to be fast and efficient, making it perfect for use on mobile devices.
- Architecture: The model uses a combination of MobileNetV2-style layers and a new block that replaces local processing in convolutions with global processing using transformers.
- Data Formats: The model supports input images in the form of pixels, but they need to be pre-processed in a specific way.
- Input and Output: The model expects input images to be in the format described above. The output of the model is a predicted mask, which is a 2D array that shows the location of objects in the image.
