How to set BB display properties

BBs and BB’s property columns, such as BB’s label and confidence, often have multiple values in a row because multiple BBs can be on a given image. In the Metrics/Examples panel, those columns typically only display the first 2-3 values due to the limited width of the columns. However, the number of values or arrays in those columns matches the number of BBs in that row. If you copy and paste the cell values, you will be able to see all the values in those cells. In the figure below, the columns highlighted by orange boxes are this type of columns with multiple values.

On a BB chart, only the bounding box rectangles for the BBs are shown by default, but you can customize what properties you want to display around the boxes when selected or not selected. When a chart is created with BBS and BBSpredicted, corresponding column names are shown on the lower left corner of the chart. You can click on the eye icons next to the column names to display or hide them independently on the chart. RightClick on BBS or BBS_PREDICTED to bring up the menu where you can customize the properties to display.

The display options under Instances in the menu include:

  • Annotate(selected): The checked properties will be displayed for the selected BBs. Default: all checked

  • Annotate: The checked properties will be displayed permanently for all BBs. Default: all unchecked

  • Colorize by: The BBs are colorized by the selected property. Default: label

  • Multiply(red): The value of color’s red channel is multiplied by the property you select. Default: all unchecked

  • Multiply(green): The value of color’s green channel is multiplied by the property you select. Default: all unchecked

  • Multiply(blue): The value of color’s blue channel is multiplied by the property you select. Default: all unchecked

Here is an example of all properties being checked under Annotate (when selected) and shown on the selected BB. For numerical properties such as confidence, a color bar next to the value shows where this value is at in the range of all data. Note that all available properties for corresponding BBs (i.e., ground truth or predicted) will be displayed under each drop-down menu. The available properties depend on what metrics you have collected and what virtual columns you have derived. Therefore, the properties that you see in your project may not be exactly the same as the example shown here.
