Keywords

💡Background Removal

Background removal is the process of eliminating the backdrop of an image to isolate the subject. In the context of the video, it is done using GIMP, a free and open-source raster graphics editor, to create a clean or transparent background for the image.

💡Selection Tools

Selection tools in GIMP are used to define a specific area of an image that the user wants to manipulate. The video mentions rectangle, ellipse, and free select tools, which are fundamental for background removal as they allow for precise selection of the image's subject.

💡Invert Selection

Inverting a selection in GIMP means to switch the selected area with the unselected area. This is a crucial step in background removal as it allows the user to target the background for deletion, leaving the subject of the image intact.

💡Clear

In the context of GIMP, 'clear' is an edit function that deletes the currently selected area. After inverting the selection to target the background, the clear function is used to remove the background from the image.

💡Fuzzy Select Tool

The Fuzzy Select Tool in GIMP is an intelligent selection tool that can identify and select areas of an image based on color and tone differences. It is particularly useful for background removal as it can automatically select the background, even in complex images.

💡Layer Mask

A layer mask in GIMP is a non-destructive editing technique that hides or reveals parts of a layer. In the video, a white layer mask is added after removing the background to fix issues, like hair details, by painting on the mask with a soft brush.

💡Paint Brush Tool

The Paint Brush Tool in GIMP is used for drawing and painting on the image. It is used with a layer mask to refine the edges of the subject, particularly around hair, to achieve a more natural look after the background has been removed.

💡Hardness

Hardness in GIMP refers to the edge softness of a brush or selection tool. A lower hardness value results in softer edges, which is useful when refining selections around intricate details like hair to avoid a harsh or artificial appearance.

💡Opacity

Opacity in GIMP determines the transparency level of a tool, brush, or layer. A full opacity white layer mask is used in the video to cover the entire image, allowing for selective painting to refine the edges without affecting the rest of the image.

💡Alpha Channel

An Alpha Channel in GIMP is an additional color channel used to store transparency information. By adding an Alpha Channel to a layer, the user can create a transparent background, which is essential for images that will be used over different backgrounds or in composites.

💡Foreground Selection Tool

The Foreground Selection Tool in GIMP is used to select parts of the image that are similar in color to the foreground color. This tool can be helpful in background removal when the subject and background have distinct color differences.
