| Abstract(in English) | A background sprite is an image composed of pixels belonging to a video object visible throughout a video segment. This paper proposes a high-quality background sprite generation method using phase-based image matching. The key issues in creating a high-quality background sprite are accurate global motion estimation and foreground object removal. Our proposed method employs (i) a phase-based sub-pixel motion estimation technique using the Phase-Only Correlation (POC) function, and (ii) a foreground object masking technique using the peak value of the POC function as a reliability measure for motion estimation. Experimental observation shows that the proposed method can generate high-quality background sprites for many practical video sequences, where the image quality is evalutaed by the PSNR between the reconstracted background image and the original one. |
