1. A method comprising:
- receiving one or more images of an object,creating feature images for the received one or more images,determining binary values for pixels in corresponding locations of said feature images and concatenating the binary values to form a binary string for said pixel,repeating the previous determination of binary values for each corresponding pixel of said feature image to form a feature map, andforming a histogram representation of the feature map.

Abstract
The invention concerns a gesture recognition method for gesture-based interaction at an apparatus. The method comprises receiving one or more images of an object; creating feature images for the received one or more images; determining binary values for pixels in corresponding locations of said feature images and concatenating the binary values to form a binary string for said pixel; repeating the previous step for each corresponding pixel of said feature image to form a feature map and forming a histogram representation of the feature map. The invention also concerns an apparatus and a computer program.

10. An apparatus comprising a processor, and memory including computer program code, the memory and the computer program code configured to, with the processor, cause the apparatus to perform at least the following:
-
receive one or more images of an object, create feature images for the received one or more images, determine binary values for each of a plurality of pixels in corresponding locations of said feature images and concatenating the binary values to form a binary string for each respective pixel, incorporate each of the binary values for each corresponding pixel of said feature image to form a feature map form a histogram representation of the feature map representative of spatial distribution features of the one or more images; and compare each histogram representation to stored histogram representations to determine whether each histogram representation is associated with an object type or a background. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A computer program product comprising a non-transitory computer readable medium and a computer program embodied thereon, the computer program comprising instructions causing, when executed on at least one processor, at least one apparatus to:
-
receive one or more images of an object, create feature images for the received one or more images, determine binary values for each of a plurality of pixels in corresponding locations of said feature images and concatenating the binary values to form a binary string for each respective pixel, incorporate each of the binary values for each corresponding pixel of said feature image to form a feature map, form a histogram representation of the feature map representative of spatial distribution features of the one or more images; and compare each histogram representation to stored histogram representations to determine whether each histogram representation is associated with an object type or a background.
