Abstract: A special-purpose convolutional learning model architecture outputs a convolutional feature map at a last of its convolutional layers, then performs binary classification based on non-semantically labeled dataset. The convolutional feature map, containing a combination of low-spatial resolution features and high-spatial resolution features, in conjunction with a binary classification output of a special-purpose learning model having transferred learning from a pre-trained learning model, may be used to non-semantically derive a segmentation map. The segmentation map may reflect both low-spatial resolution and high-spatial resolution features of the original image on a one-to-one pixel correspondence, and thus may be utilized to highlight or obscure subject matter of the image in a contextually fitting manner at both a global scale and a local scale over the image, without semantic knowledge of the content of the image.
