Web15 de mai. de 2024 · In this paper we investigate the potential of a family of efficient filters – the Gray-Code Kernels – for addressing visual saliency estimation guided by motion. Our implementation relies on the use of 3D kernels applied to overlapping blocks of frames and is able to gather meaningful spatio-temporal information with a very light computation.

Web30 de mar. de 2012 · Abstract: Motion saliency detection has an important impact on further video processing tasks, such as video segmentation, object recognition and adaptive compression. Different to image saliency, in videos, moving regions (objects) catch human beings' attention much easier than static ones. Web11 de mar. de 2024 · Two different saliency techniques were used. The first method used a built in OpenCV method known as fine grain saliency. The second method involved taking the average of the fine grain saliency image and subtracting it from the Gaussian blurred version of the image, followed by the absolute value of the new image. novavax booking perth
