Blur Image
This lesson is part of Web Developer Tools · All levels
Summary
Blur softened the image by mixing the pixel value with its neighboring pixel. The larger the blur radius, the stronger the effect and the more details are lost. These effects are used to give depth to the background, obscure a particular part, or make the look softer.
Key points
- Blur reduces sharpness by balancing the pixels around it
- A larger radius or sigma produces a stronger blur
- Gaussian blur gives greater weight to nearby pixels
- Blur on a particular area can be used to highlight the main subject
- Light blur is no guarantee of safe concealment of sensitive data
