| Abstract |
In this paper, we present a tracking technique
utilizing a simple saliency visual descriptor. Initially, we
define a visual descriptor named local similarity pattern
that mimics the famous texture operator local binary
patterns. The key difference is that it assigns each pixel a
code based on the similarity to the neighbouring pixels.
Later, we simplify this descriptor to a local saliency
operator which counts the number of similar pixels in a
neighbourhood. We name this operator local similarity
number (LSN).
We apply the local similarity number operator to measure
the amount of saliency in a target patch and model the
target. The proposed tracking algorithm uses a joint
saliency‐colour histogram to represent the target in a
mean‐shift tracking framework. We will show that the
proposed saliency‐colour target representation
outperforms texture‐colour where texture modelled by
local binary patterns and colour target representation
techniques are used. |
