How to blur a face picture how to#

Hi Adrian, IвЂ™m working on a research project for my university. TodayвЂ™s blog post is inspired by an email I received last week from PyImageSearch reader, Li Wei:

How to blur a face picture how to#

To set the Fade-out area, click with the mouse in another place and press the button.In this tutorial, you will learn how to blur and anonymize faces using OpenCV and Python. Therefore, the Fade-in area will be marked.

To make the effect gradually appear and disappear in the video, click with the mouse within the blue bar shown in the figure below and press the button. Repeat this operation until you get an appropriate shape. To do that, click on a dashed border of the mask area - a new reshaping handle appears, then drag it as you want.

The Polygon preset allows you to create a free-form area.Hover the mouse pointer over the area you want to move until it turns into a cross with arrows, hold the mouse button and drag the mask to a new position. Change the Rectangle or Ellipse mask positionВ on the screen.Adjust the blur area size by dragging the resize handles in the corners of the mask area.You can additionally modify the mask area: Areas outside of the applied mask remain unchanged. To specify the blur area for any of the Blur effects, select the necessary preset from the Mask list: Rectangle, Ellipse, or Polygon (the None option is selected by default that allows to apply the effect to the entire image). If you do not want to apply the effect to an entire image, you can set the necessary part of the frame that the effect will be applied to. This parameter specifies how far the original pixels are shifted. Distance - a distance from 1 to 100 pixels (by default, it is set to 40).For example, the value of 0 produces a horizontal blur, the value of 90 produces a vertical blur. This parameter specifies the angle of the movement. Angle - an angle between -180В° to 180В° (the default value is 45В°).Higher values produce the more intensive blur effect.ДЄpplying the Motion Blur effect, you can adjust the following parameters: Drag the slider or type in the necessary numeric value into the entry field on the right.ДЇor the Gaussian Blur effect, the Size parameter can be set to a value from 0 to 50 (the default value is 10). If necessary, you can change it specifying a value from 0 to 100. By default, it is set to the maximum value. The Blur effect allows to adjust the BlurВ level. The screenshots below display an example of the video picture before and after applying the Motion Blur effect (the effect is applied to the entire image):ДЄdjust the effect properties if necessary Motion Blur gives the impression of motion in the image as if the photo had been taken when the object was moving. The following images demonstrate an example of the video picture before and after applying the Gaussian Blur effect (the effect is applied to the entire image): Gaussian Blur uses a mathematical equation to calculate the transition between adjacent pixels, that results in a defocused effect. In the figures below you can see an example of the video picture before and after applying the Blur effect (the effect is applied to the entire image): Blur is the basic blur effect that reduces contrast between adjacent pixels by lightening pixels next to well-defined edges and shadows.

Generally, any of the BlurВ effects allows you to smooth and soften edges and details in the video image. Select the Blur effect and add it to the timeline
