The FAQs in this article are related to LandingLens.
How many images do I need to upload for model training?
Since every use case is different, there is no recommended set number. This number generally depends on these factors:
- How elaborate the object to identify is
- How many types of objects there are
- How the object looks
For example, a hammer with a broken handle would require fewer images than a printed circuit board that has several intricate parts.
What image file types does LandingLens support?
LandingLens supports BMPs, JPEGs, and PNGs for all Project Types.
Object Detection also supports Pascal VOC files. Pascal VOC (Visual Object Classes) is a file format that includes the label details of its paired image. It essentially tells the platform where a label is on the associated image.
What types of labeling tools are available?
LandingLens offers different Project Types, and each Project Type has a different labeling tool.
|Project Type||Label Tool|
|Object Detection||Bounding boxes (rectangles) to outline an object.|
|Segmentation||Pen-like tools to "paint" specific pixels.|
|Classification||Classify images after upload using Classes. Or, upload "classified" folders; LandingLens will automatically classify images based on the titles of the folders. (Classification looks at all the pixels in an image.)|
Do you have tools to evaluate consistency among different Labelers?
Yes! LandingLens offers Agreement-Based Labeling that allows multiple Labelers to label the same images. The platform will then rank those images based on levels of consistency. For more information, go here.
What types of augmentation tools are available?
LandingLens offers these augmentation tools:
- Random brightness
- Blur, motion blur, and gaussian blur
- Hue saturation
- Random contrast
- Horizontal and vertical flips
- Random rotate
- Random augmentation
Can I upload pre-labeled images to LandingLens?
Yes! Pre-labeled image files must be in a Pascal VOC file format. Pascal VOC (Visual Object Classes) is a file format that includes the label details of its paired image. It essentially tells the platform where a label is on the associated image.
Can I upload zipped files to LandingLens?
All files must be unzipped before uploading them to LandingLens.
Does LandingLens keep folder hierarchies on upload?
LandingLens simplifies folder structures and flattens all files. Let's say you have one folder (Folder A) and two subfolders (Folder B and Folder C). If you upload Folder A, LandingLens will upload all images from Folders A, B, and C, as if they came from the same folder.
However, if you upload Classified Media to a Classification Project, LandingLens will ignore any subfolders. Referring back to the example above, if you upload Folder A, only the images in Folder A will be uploaded; the images in Folders B and C will not be uploaded.
