Spontaneous retinal Venous Pulsations SVP are rhythmic changes in the caliber of the central retinal vein and are observed in the optic disc region ODR of the retina Its absence is a critical indicator of various ocular or neurological abnormalities Recent advances in imaging technology have enabled the development of portable smartphone based devices for observing the retina and assessment of SVPs However the quality of smartphone based retinal videos is often poor due to noise and image jitting which in return can severely obstruct the observation of SVPs In this work we developed a fully automated retinal video stabilization method that enables the examination of SVPs captured by various mobile devices Specifically we first propose an ODR Spatio Temporal Localization ODR STL module to localize visible ODR and remove noisy and jittering frames Then we introduce a Noise Aware Template Matching NATM module to stabilize high quality video segments at a fixed position in the field of view After the processing the SVPs can be easily observed in the stabilized videos significantly facilitating user observations Furthermore our method is cost effective and has been tested in both subjective and objective evaluations Both of the evaluations support its effectiveness in facilitating the observation of SVPs This can improve the timely diagnosis and treatment of associated diseases making it a valuable tool for eye health professionals
