salMaps = batchSaliency(images)
Computes the saliency maps for a number of images.
images can be one of the following:
- a vector of Image structures as obtained from initializeImage
- a cell array of file names of image files
- the name of a directory - all files in that directory are assumed
to be images
[salMaps,fixations] = batchSaliency(images,numFixations)
Computes the saliency maps and the coordinates of the first
numFixations fixations. fixations is a cell array with one cell
for each image. Each cell is of size numFixations x 2.
[salMaps,fixations] = batchSaliency(images,numFixations,params)
Uses params as the saliency parameters. By default, the parameters
from defaultSaliencyParams are used.
