Study Notes
Masking Guide
- Masking is the process of drawing rectangles or squares to cover full products in a probe to identify separate products in a system.
- The goal of masking is to use machine-learning methods to automatically detect and label products in a given probe.
- Masking is necessary because there is no automatic masking algorithm available, so QATs (Quality Assurance Team) manually draw masks around products as well as they can.
Importance of Proper Masking
- Proper masking is crucial for the success of the process, as improper masking can lead to invalid votes in voting, harming the engine's training and accuracy, damaging the accuracy of voting, and affecting PPA calculation.
- Proper masking enables the system to correctly identify and label products, ensuring accurate results.
Masking Environment
- Masking is done in a special environment called "Masking" in SMART.
- This environment provides features such as filling masks with a dark background, resizing masks, dragging masks, and changing mask colors.
Masking Features
- The system has a feature called "Duplicate Mask Button" that enables creating duplicate masks by clicking on an icon.
- The "Resize Button" allows selecting a mask by double-clicking, enabling the drawing of overlapping masks, resizing buttons, and deleting buttons.
Masking Guidelines
- All visible products should be masked in the probe, considering generic tagging rules.
- The mask should be drawn exactly on the SKU border, not too narrow or too wide.
- Masks should also be drawn on empty spaces.
Specific Masking Scenarios
- If products are partially covered, it is preferable to draw masks with a small overlap rather than drawing a smaller mask than the actual product size.
- For clip strips and hanging products, each SKU should be masked individually.
- For hoppers, baskets, and packages, one single mask should be drawn for the entire unit.
- For transparent packs, each individual product should be masked, while for non-transparent packs, the entire unit should be masked.
- For tilted products, one big mask should be drawn around the group of products.
- For rotated probes, the probe should be canceled using the "Probe is Rotated" option.
Masking POSMs (Point of Sale Materials)
- All POSMs should be masked.
- POSM masking should be avoided unless the products are covered by a POSM, in which case each product should be masked individually.
Masking Probes with Quality Issues
- If the probe is too blurry, the QAT can skip masking and continue to the next probe.
- If the image is taken from a big distance, making it impossible to recognize SKUs, the QAT can skip masking.
- Only visible SKUs should be masked in a probe, and unclear products can be ignored.
Masking Empty Spaces
- QATs should mask all empty spaces where possible to put at least one product.
- The mask should be drawn around the entire empty space on the shelf.
- However, if an empty space is not suitable for holding products, no mask should be drawn.### Masking Guidelines
- Mask only visible price labels in the probe, do not mask products.
- Special guidelines from the R&D team may apply.
Masking Menus
- Mask menu items one by one, following menu recognition rules.
- Consider special guidelines from the R&D team, if applicable.
Bad Masking
- Common mistake: products without masks at all.
- Mask quality issues: masks too narrow, not drawn at all, or drawn incorrectly.
Partial Masking
- Mask only products with tags, do not mask other products.
- If a product does not have a tag, a live alert will pop up, and the incorrect masking will disappear.
Rectification for Masking Tasks
- Mechanism in SMART rectifies images from Dome cameras to support "Fresh" recognition for Tesco and Aldi.
- Rectification is done before creating a masking task, and the masker will mask the rectified images.
Delete Masks When Screen Size is Changed
- Solution to avoid masking offset issue: delete masks and notify masker with a pop-up message if screen size is changed during the task.
Special Masking Guidelines
- Piles Masking: unclear piles (bad ordered) should be masked as one unit.
- Confectionary Masking: small confectionary products laying on top of each other should be masked once as one unit.
- Cookies & Crackers: well-ordered piles should be masked separately.
- FRONT PRODUCTS: only facing/front products should be masked.
- BOXES: boxes with multiple small products in them should be masked as one unit.
Full Guided Masking (FGM)
- Flow: 1st cycle of voting, followed by masking task, and if needed, another cycle of voting.
- SLA for both voting and masking is 24 hours.
- Process: maskers can mask according to tagged products without recognition confusion.
- Full Guided Masking (FGM) – Empty Masking: QATs should mask all empty space separately with one tag each.
Full Guided Masking (FGM) – Transparent Packs
- Scenario 01: transparent pack with tags on each product - mask each product with a tag.
- Scenario 02: transparent pack with one tag on the pack - mask the entire transparent package.
Mssing Mask Alert – PM & FGM
- Alert 01: missing masks - not all tags are masked; confirm and continue only after ensuring all relevant tags are masked.
- Alert 02: missing masks - zero masks were drawn; cancel the probe if only dislocated/unnecessary tags are present, and mention the cancelation reason properly.
