Methods and systems for providing fast semantic proposals for image and video annotation

A system for providing fast semantic proposals for image and video annotation, comprising:

• an extraction algorithm executed on a processor operable for, given an input image to be segmented for a region of interest, extracting one or more image planes from the input image;
• a linearization algorithm executed on the processor operable for linearizing each of the one or more image planes to generate a one-dimensional array corresponding to the one or more image planes to extract an input feature vector per image pixel for the one or more image planes;
• a feature abstraction algorithm executed on the processor operable for abstracting features for the region of interest using a modified echo state network model utilizing a reservoir including a layer of connections between reservoir nodes, wherein the reservoir increases feature dimensions per pixel location to multiple dimensions followed by feature reduction to one dimension per pixel location, wherein the echo state network model comprises both spatial and temporal state factors for the reservoir nodes associated with each pixel vector, and wherein the echo state network model outputs a probability image that is thresholded;
• a post-processing algorithm executed on the processor.
