Element
The target of the search query
The search element represents the target of the search query. This can be a class, an annotation, or a specific dataset. Search elements can be combined with other search elements by logic to refine the search query.
Can image like the query block equals to the where-clause of SQL.
Dataset
key | value | type | element logic |
---|---|---|---|
dataset | The dataset name. | string | = != IN () |
<Example> Find all the data in dataset 001
Dataslice
key | value | type | element logic |
---|---|---|---|
dataslice | The dataslice name. | string | = != IN () |
<Example> Find all the data in dataslice 001 or data slice 002
IQA
The image quality assessment.
There are 7 types of IQA items: lightness, contrast, colorfulness, max color Kurtosis, BRISQUE, Laplacian-blur, and FFT-Blur.sql
key | value | type | element logic |
---|---|---|---|
iqa.lightness | The lightness of the image. | number | = > >= < <= != BETWEEN |
iqa.contrast | The contrast of the image. | number | as above |
iqa.colorfulness | The colorfulness of the image. | number | as above |
iqa.max_color_kurtosis | The max_color_kurtosis of the image. | number | as above |
iqa.brisque | The brisque of the image. | number | as above |
iqa.laplacian_blur | The laplacian_blur of the image. | number | as above |
iqa.fft_blur | The fft_blur of the image. | number | as above |
<Example> Find all the data iqa lightness > 30
Class
The class follows the ontology settings. In the context of your search syntax, the element “class.name” specifically refers to the classification of an object (ex.bounding box) in an image or a set of images.
Note
The class.name does not indicate whether an image or a dataset contains a certain class of objects as a whole. Instead, it is used to find specific instances of objects within the bounding boxes in the data.
key | value | type | element logic |
---|---|---|---|
class.name | The class name. | string | = != IN () |
<Example> Find all the data with object class car.
Hint
Use 'class IS NULL' in your search query to find items that do not have a specified object class.
Class with Attribute
The class attributes follow the ontology settings.
key | value | type | element logic |
---|---|---|---|
class.attribute.name | The name of the attribute. | string | = != IN OR AND |
class.attribute.value | The value of the attribute. | Depends on the tag type - vec : string - number : number - boolean : boolean text type not included in the query. | vec, text and boolean: = != number: = > >= < <= != |
<Example> Find the person age between 28~30, year in 1995, 1996, 1997.
Annotation
The target annotations result. It can be ground truth or model predictions.
key | value | type | element logic |
---|---|---|---|
annotation | Ground Truth or the model name. | string | = != IN () |
annotation.confidence | The confidence score of the object. | number | = > >= < <= != |
<Example> Find all the data with ground truth, model-a annotations.
<Example> Find all the data with confidence score > 50% annotations.
Object
The object information includes height, width, length, area, and the cuboid object distance and the points included.
key | value | type | unit | element logic |
---|---|---|---|---|
object_size.height | The object size (height) | number | px | = > >= < <= != |
object_size.width | The object size (width) | number | px | as above |
object_size.length | The object size (length) | number | px | as above |
object_size.area | The object area | number | px^2 | as above |
object_cuboid.distance | The object cuboid distance. It is only available for point cloud data cuboids. | number | m | as above |
object_cuboid.point | The object cuboid included points. It is only available for point cloud data cuboids. | number | points | as above |
Example:
Find all the data with object size height < 100px.
Find all the data with object size area < 40px^2.
Find all the data with cuboid center distance to origin > 10m
Find all the data with cuboid containing < 5 pcd points
Tag
The project taggings.
key | value | type | element logic |
---|---|---|---|
tag.name | The name of the tag. | string | =, In != |
tag.value | The value of the tag. | Depends on the tag type - vec : string - num : number - boolean : boolean text type not included in the query. | vec, text and boolean: = != IN () number: = > >= < <= != |
<Example> Find the weather of sunny or rainy.
