Image filters are primarily used to edit an image using computer software. An image filter generally changes the image at the pixel level, meaning each pixel individually is affected. It can be applied to 2-D and 3-D images. Typically, the image filter process includes options such as:

• Editing the color scheme/theme/contrast of the image
• Adjusting image brightness
• Adding effects to the image
• Changing the texture

The term image filter may also refer to the process of filtering (excluding) images from data, folders or Web searches.
