Method, system and apparatus for stabilising frames of a captured video sequence

An apparatus for stabilising frames of a captured video sequence, the apparatus comprising:

• means for receiving a first plurality of reference patch locations in a reference frame;
• means for receiving first reference patch alignment data for each of the plurality of reference patch locations;
• means for determining a first stable frame and a subsequent stable frame from a first plurality of frames based on the first plurality of reference patch locations and reference patch alignment data;
• means for determining a second plurality of reference patch locations using image data from the first stable frame, the second plurality of reference patch locations being determined concurrently with determining the subsequent stable frame from the first plurality of frames, wherein image data for the determined second plurality of reference patch locations is extracted from the subsequent stable frame;
• and
• means for determining a second plurality of stable frames of the captured video sequence with respect to the reference frame using the second plurality of reference patch locations and the extracted image data.

A system for stabilising frames of a captured video sequence, the system comprising:

• a memory for storing data and a computer program;
• a processor coupled to the memory for executing the computer program, said computer program having instructions for:
• receiving a first plurality of reference patch locations in a reference frame;
• receiving first reference patch alignment data for each of the plurality of reference patch locations;
• determining a first stable frame and a subsequent stable frame from a first plurality of frames based on the first plurality of reference patch locations and reference patch alignment data;
• determining a second plurality of reference patch locations using image data from the first stable frame, the second plurality of reference patch locations being determined concurrently with determining the subsequent stable frame from the first plurality of frames, wherein image data for the determined second plurality of reference patch locations is extracted from the subsequent stable frame;
• and
• determining a second plurality of stable frames of the captured video sequence with respect to the reference frame using the second plurality of reference patch locations and the extracted image data.

A computer readable medium having a program stored on the medium for stabilising frames of a captured video sequence, the program comprising:

• code for receiving a first plurality of reference patch locations in a reference frame;
• code for receiving first reference patch alignment data for each of the plurality of reference patch locations;
• code for determining a first stable frame and a subsequent stable frame from a first plurality of frames based on the first plurality of reference patch locations and reference patch alignment data;
• code for determining a second plurality of reference patch locations using image data from the first stable frame, the second plurality of reference patch locations being determined concurrently with determining the subsequent stable frame from the first plurality of frames, wherein image data for the determined second plurality of reference patch locations is extracted from the subsequent stable frame;
• and
• code for determining a second plurality of stable frames of the captured video sequence with respect to the reference frame using the second plurality of reference patch locations and the extracted image data.
