vision.Deinterlacer System object

Package: vision

Remove motion artifacts by deinterlacing input video signal


The Deinterlacer object removes motion artifacts by deinterlacing input video signal.

    Note:   Starting in R2016b, instead of using the step method to perform the operation defined by the System object™, you can call the object with arguments, as if it were a function. For example, y = step(obj,x) and y = obj(x) perform equivalent operations.


H = vision.Deinterlacer returns a deinterlacing System object, H, that removes motion artifacts from images composed of weaved top and bottom fields of an interlaced signal.

H = vision.Deinterlacer(Name,Value) returns a deinterlacing System object, H, with each specified property set to the specified value. You can specify additional name-value pair arguments in any order as (Name1, Value1,...,NameN,ValueN).

Method used to deinterlace input video

Specify how the object deinterlaces the input video as one of Line repetition | Linear interpolation | Vertical temporal median filtering. The default is Line repetition.


Indicate if input data is in row-major order

Set this property to true if the input buffer contains data elements from the first row first, then the second row second, and so on.

The default is false.

Create a deinterlacer object.

hdinterlacer = vision.Deinterlacer;

Read an image with motion artifacts.

I = imread('vipinterlace.png');

Apply the deinterlacer to the image.

clearimage = hdinterlacer(I);

Display the results.

title('Original Image');
figure, imshow(clearimage);
title('Image after deinterlacing');


This object implements the algorithm, inputs, and outputs described on the Deinterlacing block reference page. The object properties correspond to the block parameters.

Introduced in R2012a
