Clutter B
Number Of Images: 139 Image Size: 1024 x 768 Comments: Like
Clutter A, this image set shows a background environment consisting of a set
of ÒofficeÓ objects. The purpose of the image set is to provide a set of
clutter scenes to composite with the bluescreened images in the chair,
redchair, and cart image sets.
The lower left portion of the images is mainly empty so that the
bluescreened images can be added in to make realistic-looking views with
minimal adjustment. The main
difference between Clutter A and Clutter B is that some of the objects are
different: in particular the table and monitor are present here. Clutter B could be useful to test how
algorithms trained using Clutter A as training data react to changes in
clutter objects. The set of
views spans roughly 60 degrees of rotation in the plane parallel to the floor,
and variation in scale and camera elevation is about the same as for the cart
and chair images. Specifically, the objects are about 2-3 m away from the
camera, the height of the camera is between 1.5 m and 2m, and the total
variation in object scale across all views is about 20%. To induce appearance
variation in the background between views, we modified the poses of each
background object and shuffled their relative positions every 5 to 8 images.
The camera translates from side to side between views and rotates slightly. Vista Parameters: (sigma, lowThreshold,
highThreshold,minimumEdgeLength, accuracy, granularity, magnitude) =
