How to Use

1. Upload Image

Click the upload area or drag an image to upload. Supports JPG, PNG, and WebP formats.

2. Adjust Settings

Adjust color map, sensitivity, and blur amount. Higher sensitivity emphasizes depth differences, higher blur produces smoother results.

3. Run Estimation

Click "Start Depth Estimation" to begin analysis. Brightness, color, and edge information are combined to estimate depth.

4. Review and Download

Compare original and depth map side by side. Download as PNG if satisfied.

Frequently Asked Questions

What is a depth map?

A depth map represents how far each pixel in an image is from the camera. Bright areas indicate closer objects, while dark areas represent distant objects.

What algorithm is used?

It combines luminance analysis, Sobel edge detection, color saturation analysis, and Gaussian blur to estimate depth. Processed in real-time in the browser without deep learning models.

What types of images work best?

Landscape photos, indoor scenes, and portraits with clear foreground and background separation produce the best results. Solid backgrounds or abstract patterns may yield less accurate results.

What are the differences between color maps?

Grayscale shows basic black-and-white depth. Rainbow uses spectrum colors. Thermal mimics thermal camera style. Ocean uses blue-green tones to represent depth.

Is my privacy safe?

Yes, all processing is done locally in your browser and images are never uploaded to any server. Works even without internet connection.

Notice

  • This tool uses heuristic-based estimation and may be less accurate than deep learning models.
  • Complex scenes or repetitive textures may result in inaccurate depth estimation.
  • All processing is done locally in your browser and images are not uploaded to any server.

Learn About Image Depth Maps

How Depth Maps Work

A depth map is an image that represents how far each pixel is from the camera as a brightness value. Bright pixels indicate nearby objects, while dark pixels represent distant objects. This tool uses a heuristic-based algorithm that combines luminance analysis, Sobel edge detection, color saturation analysis, and vertical position bias to estimate depth. Applying Gaussian blur reduces noise and produces a smoother depth map. All calculations are processed in real time in the browser.

Advances in AI-Based Depth Estimation Technology

Recent advances in deep learning have made it possible to estimate precise depth even from a single image. AI models such as MiDaS, DPT, and Depth Anything learn from large datasets to understand spatial depth similarly to how humans perceive it. Traditional stereo camera methods use the parallax between two cameras, but AI monocular depth estimation generates high-accuracy depth maps from just a single photo. Combined with LiDAR sensors, even more precise 3D environment perception is possible in autonomous vehicles, drones, and robotics.

Applications of Depth Maps

Depth maps are used as a core technology across many fields. In computer graphics, they are used for bokeh background blur effects, 3D model generation, and virtual reality (VR) content creation. The portrait mode on smartphone cameras uses depth maps to naturally blur backgrounds. Self-driving cars use depth maps generated from cameras and LiDAR to determine distances to surrounding obstacles. In medicine, depth information is also used for 3D reconstruction of endoscopic images and precise control of surgical robots. In game development, depth maps are essential for converting real photos into 3D environments.
