Model overview
The sks model, created by simbrams, is a C++ implementation of a sky segmentation model that can accurately segment skies in outdoor images. This model is built using the U-2-Net architecture, which has proven effective for sky segmentation tasks. While the model does not include the "Density Estimation" feature mentioned in the original paper, it still provides high-quality sky masks that can be further refined through post-processing.
Model inputs and outputs
The sks model takes an image as input and outputs a segmented sky mask. The input image can be resized and contrast adjusted to optimize the model's performance. Additionally, the model can be configured to keep the inference engine alive for faster subsequent inferences.
Inputs
- Image: The input image for sky segmentation.
- Contrast: An integer value to adjust the contrast of the input image, with a default of 100.
- Keep Alive: A boolean flag to keep the model's inference engine alive, with a default of false.
Outputs
- Segmented Sky Mask: An array of URI strings representing the segmented sky regions in the input image.
Capabilities
The sks model demonstrates strong sky segmentation capabilities, effectively separating the sky from other elements in outdoor scenes. It performs particularly well in scenes with trees, retaining much more detail in the sky mask compared to the original segmentation. However, the model may struggle with some special cloud textures and can occasionally misclassify building elements as sky.
What can I use it for?
The sks model can be particularly useful for applications that require accurate sky segmentation, such as image editing, atmospheric studies, or even augmented reality applications. By isolating the sky, users can easily apply various effects, adjustments, or overlays to the sky region without affecting the rest of the image.
Things to try
One interesting aspect of the sks model is the post-processing step, which can further refine the sky mask to improve its accuracy. You may want to experiment with different post-processing techniques to see how they can enhance the model's performance in various outdoor scenarios.
Additionally, the model's speed and efficiency are important factors to consider, especially for real-time applications. The maintainer mentions plans to explore more efficient model architectures, such as a real-time model based on a standard U-Net, to improve the model's inference speed on mobile devices.
