attributes
Attributes in the context of the VisionAI format refer to an alias assigned to element data that can be nested within geometric object data. For instance, a bounding box may have attributes related to its score, visibility, or other features. These attribute values can be nested within the object (ex. boundingbox) data itself.
Schema
Example
attributes {}
An attribute can be any combination of the following types below. Each type is an array. All values with the same type will be in the same array.
name | description | type | required |
---|---|---|---|
boolean | The boolean type attribute means a result that can only have one of two possible values: true or false. | array of objects | false |
num | The number type attribute defines a floating-point number and is defined by a name key, and val key. | array of objects | false |
text | The text type attribute is a string to represent textual information. | array of objects | false |
vec | The vec type attribute is an array of text. It represents the options of the attribute and possibly has the same properties as the other generic attributes. | array of objects | false |
attribute_type objects
name | description | type | required |
---|---|---|---|
name | The name of this attribute. | string | true |
val | The value of this attribute follows the table defined above. ➤ boolean: boolean ➤ num: float ➤ text: string ➤ vec: array of strings | describe in the description | true |
NOTE: The attribute name and the vec type array items name may only contain lowercase letters, numbers, and hyphens (-), and must begin and end with a letter or a number. Each hyphen (-) must be preceded and followed by a non-hyphen character. The name must also be between 3 and 40 characters long.
Use Case
bbox with attributes
To describe a bbox dataset with one camera sensor:
sensor: camera (#camera1)
ontology:
people
ischild - boolean (static info)
direction - front, left, right, back (dynamic info)
age - number (static info)
car
color - white, silver, blue, red, black (static info)
truck
bus
