Topaz Mask AI is a professional image masking and cutout software based on artificial intelligence technology. It intelligently identifies the foreground and background in an image, greatly simplifying the cutout process for complex subjects (such as hair, smoke, transparent gauze, and intricate vegetation), providing photographers, designers, and digital artists with an efficient and precise masking creation solution.

I. Detailed Explanation of the Core Interface and Workspace

After launching the software, the main interface is primarily divided into the following core areas:

• Top Menu Bar: Contains standard menu items such as File, Edit, View, Window, and Help.
• Left Tool Panel: Vertically arranges the core operation tools.
  • Brush Tool: Used to manually paint the foreground (green) and background (red).
  • Fill Tool: Used to quickly fill large areas as foreground or background.
  • Compute Mask Button: The core button that triggers AI computation to generate the initial mask.
  • Erase/Restore Brush: Used to correct erroneous areas of the mask after AI computation.
  • Edge Brush: Specifically used to refine edge transitions, handling semi-transparency or hair details.
  • Hand & Zoom Tool: Used for navigating the image.
• View Area: Displays the image currently being edited. You can switch between “Original,” “Mask,” “Transparent,” and “Composite” views via the tabs at the bottom to preview the cutout result in real time.
• Properties Panel:
  • Mask Properties: Adjust the overall smoothness, feathering, and shift edge of the mask.
  • Edge Properties: Fine-tune the edge width, opacity, and smoothness.
  • Color Decontamination: Eliminate color fringing caused by background color bleeding at the edges.
  • Output Settings: Choose the final export as PNG or TIFF with a transparent channel, or composite directly onto a new background.

II. Complete Workflow: From Opening to Export

1. Create/Open a Project

Step 1: Launch Topaz Mask AI. In the startup window, click the “Open Image” button, or go to the menu bar File > Open Image… (shortcut ⌘Cmd + O) to import an image you need to cut out.

Step 2: Once the image is loaded, the software will automatically enter the editing interface. It is recommended to first use the Zoom tool (Z) in the left toolbar or the shortcuts ⌘Cmd + +/⌘Cmd + - to enlarge the key areas of the image for precise operation.

2. Mark Foreground and Background

This is the key step that guides the AI in recognizing the image content.

Step 3: Select the Brush Tool from the left toolbar (shortcut B).

Step 4: On the image, use green to mark the foreground subject that needs to be kept. For example, when cutting out a person, paint green over the person’s body (excluding complex hair edges).

Step 5: Switch to red to mark the clear background areas. Paint red over the background areas (such as sky, walls). The marking principle is: the foreground and background marking lines should overlap slightly and ensure all areas are covered.

3. Compute and Generate Initial Mask

Step 6: After completing the basic markings, click the blue “Compute Mask” button in the center of the left toolbar (shortcut ⌘Cmd + M). The software will use AI algorithms to analyze your markings and generate an initial mask.

Step 7: After computation is complete, click the “Mask” tab at the bottom of the view area to view the black-and-white mask (white is kept, black is removed). Switch to the “Transparent” tab to preview the transparent background effect after cutting out.

4. Fine-Tuning and Optimizing the Mask

The initial mask generated by AI usually needs fine-tuning.

Step 8: Under the “Mask” or “Transparent” view, check for flaws. Select the Erase Brush (shortcut E) to erase excess parts in the mask (background mistakenly retained). Select the Restore Brush (shortcut R) to restore missing parts in the mask (foreground mistakenly removed).

Step 9: For semi-transparent edges such as hair and gauze, switch to the “Original” view and use the Edge Brush (shortcut Y) to gently paint along these complex edges. The software will intelligently preserve details and transparency.

Step 10: In the “Edge Properties” panel on the right, fine-tune sliders such as Edge Width and Transparency to make the edge transition more natural.

Step 11: If you notice background color residue on the edges, check and adjust the “Color Decontamination” option on the right.

5. Preview and Export the Final Result

Step 12: Click the “Composite” tab to preview the composite result of the cut-out subject and the new background. You can test it by adding a custom background image via File > Add Background….

Step 13: Once you are satisfied with the result, you are ready to export. In the “Output Settings” at the bottom of the right panel, select the output type:

• Foreground Only: Export only the foreground with a transparent channel (PNG format recommended).
• Foreground on Custom Background: Composite the foreground onto a specified background image.

Step 14: Click the blue “Save” button in the lower right corner of the software interface, or go to the menu bar File > Save As… (shortcut ⌘Cmd + Shift + S) to set the file save path, format, and name, then click Save to complete the export.

III. Advanced Tips for Common Features

1. Flexible Use of the “Keep” and “Exclude” Brushes: During the marking stage, there is no need to pursue perfect outlines. For the interior of foreground objects, use large green strokes; for clear background areas, use large red strokes. The AI can understand your intent and perform intelligent segmentation at the boundaries.
2. Using Edge Properties to Handle Flyaway Hair: For scattered strands of hair, after AI processing, use the Edge Smudge Tool (Y) to smudge along the direction of the hair, and appropriately increase the Transparency value in Edge Properties to create a more realistic semi-transparent hair effect.
3. Multi-Pass Computation by Region: For extremely complex images (such as a tree full of leaves), you can process them region by region: first mark and compute one portion, apply the mask, then repeat the process for the remaining portions, and finally merge the results.

IV. Common Issues & Solutions

• Issue 1: After AI computation, mask edges are too harsh or details are lost.
  • Solution: Check whether the initial marking covered enough of the edge area. Use the Edge Refine Tool (Y) to re-paint the edges in the original view. In the right panel, lower the Smoothness value under Mask Properties and increase the Edge Width under Edge Properties.
• Issue 2: The cut-out image has white fringing on the edges or residual background color.
  • Solution: Enable and adjust the “Color Decontamination” slider on the right. You can also try fine-tuning the “Shift Edge” slider under “Mask Properties” to contract the edges inward.
• Issue 3: Results are unsatisfactory when processing transparent or semi-transparent objects (e.g., glass cups, wedding veils).
  • Solution: During the marking stage, mark the semi-transparent areas with green (foreground). After AI computation, focus on using the Edge Refine Tool (Y) to paint in that area, and significantly increase the Transparency value under Edge Properties.
