While prior depth from focus and defocus techniques operated on laboratory scenes, we introduce the first depth from focus (DfF) method capable of handling images from mobile phones and other hand-held cameras. Achieving this goal requires solving a novel uncalibrated DfF problem and aligning the ...

When you add wallpaper with distinct elements, your iPhone splits it into several layers of depth. To do this, iOS utilizes the built-in neural engine to detect depth information from your wallpaper to separate subjects you want to appear in focus from other elements of the chosen back...

This system is based on the concept of depth from focus, and robustly locates static and moving obstacles as well as stairs and dropoffs with adequate accuracy for obstacle avoidance. We describe an implementation of this vision system on a mobile robot as well as real-world experiments both ...
Tip and tricks guys, use the Aperture Mode in your Huawei mobile phone to capture great image with depth of field. 1st. Open the Camera 2nd. Find the Aperture mode 3rd. Choose what you prepare number of aperture from F0.95 to F14. 4th. Find the subject do you want to apply the de...
Sometimes we capture that perfect moment with our camera and then realize that the subject is not isolated enough from the background and the background is really distracting. Now what? Well, you can use the lens blur feature in Photoshop to keep the subject in focus while blurring the...
The comparison results show that, compared with the white light source before optimization, the white light source after optimization is more stable, and the DOF has also increased from 400 μm to 800 μm. Figure 6. Convergence behaviors of each approach for the depth of focus (the ...
