Robust Visual Correlation Tracking
Algorithm 1
Proposed tracking algorithm.
Input
: The
th frame video sequence
, Initial target position
and scale
.
Output
: Detected target position
and scale
.
Repeat
:
Crop out the searching region in frame
according to
and
, and extract the sample
;
//Position Detection
:
(
) Compute the response
with
,
and
using (
12
);
(
) Find the target position
which maximizes
.
//Scale Prediction
:
(
) Extract a sample
from
at
and
;
(
) Compute the response
with
,
and
using (
16
);
(
) Find the target scale
which maximizes
.
//Model Online Update
:
(
) Extract samples
and
from
at
and
;
(
) Update
using (
13
), (
14
) and update
using (
9
);
(
) Update
using (
13
), (
14
) and update
using (
9
).
Until the End of the Video Sequence
