Deep Focus Effects and Background Blur Techniques
In an exciting fusion of image processing, computer graphics, and web development, a new project showcases the creation of bokeh effects on flat photos using AngularJS, Google Camera Lens Blur, and the Depthy app.
The project, inspired by Magic Eye images, begins with capturing or preparing a depth map. Google Camera's Lens Blur mode can create a photo with a depth map that simulates shallow depth-of-field blur. This depth data can be extracted or used to reapply blur selectively. Alternatively, the Depthy app, which specializes in generating or visualizing depth in flat images, can be used to create depth maps interactively.
AngularJS is then employed to implement or control the blur effect dynamically. The web interface takes a photo plus a depth map, and applies a selective blur filter based on depth information. This includes loading the flat image and its depth map, running a shader or canvas-based blur effect, and allowing user controls for blur radius and transition softness.
The workflow combines these tools effectively. A photo is taken in Google Camera's Lens Blur mode, which captures depth data embedded in the photo. The image and depth map are then loaded in the AngularJS app, and a rendering step applies dynamic Gaussian blur or bokeh blur based on depth values.
For a more realistic bokeh, simulate lens aperture shape and light effects in the blur. Use high-resolution depth maps for better blur edges. If your photo lacks embedded depth data, the Depthy app can help you visualize and export depth maps. Consider using WebGL libraries with AngularJS for efficient real-time blur rendering.
While a detailed step-by-step AngularJS tutorial combining exactly Google Camera Lens Blur and Depthy app was not found, these technologies commonly integrate in this manner for synthetic bokeh: capture depth → process depth map → apply selective blur programmatically (e.g., in AngularJS). This approach moves beyond simple overlay or Photoshop textures, enabling interactive bokeh effects on flat images.
For a simplified alternative, Photoshop-style overlays or applications like Luminar Neo provide automated bokeh effects without programming. However, to achieve dynamic, custom bokeh in a web environment using AngularJS, leveraging depth maps from Lens Blur photos and Depthy is the standard technique.
The project culminates in a final image featuring a "bokeh" effect, further enhanced with a parallax effect using Depthy. Users can load their own images, view and adjust the depth map, and generate the final "bokeh" image. A video demonstrating the 3D parallax effect can be viewed here: 3D Parallax Effect Video. Additional renderings were produced to showcase the project, including a partial 3D model of the subject.
- This project, inspired by Magic Eye images, not only utilizes AngularJS for dynamic blur effect control but also integrates technology from home-and-garden (Depthy app) and data-and-cloud-computing (Google Camera Lens Blur) to create a lifestyle application that simulates bokeh effects on flat photos.
- In the future, users might expect more advancements in lifestyle applications, as they combine elements of image processing, computer graphics, web development, and technology to offer interactive bokeh effects on flat photos, just like this project does.
