An image stitching method applied to an image stitching device having at least two image capturing units and an operation processing unit includes acquiring at least two images adjacent by each other, detecting an overlapped region of the two adjacent images, compiling statistics of image information about the overlapped region of the two adjacent images, utilizing the image information to compute a compensation function, and adjusting at least one of the two adjacent images according to the image information to make the image information of the two adjacent images into harmony.

Image stitching method and image stitching device

A particle filter is suitable for performing particle filtering on a frame to track a particular object in the frame. The particle filter includes a frame cache, an observation model generator, and a particle filter controller. The frame cache is connected to a system memory through a system bus, in which the system memory stores all image blocks of the frame; and the frame cache obtains the at least one image block of the frame from the system memory and stores the obtained image block. The observation model generator reads at least one pixel from the frame cache, and generates an observation model corresponding to the object and the read image block according to the read pixel. The particle filter controller obtains the observation model from the observation model generator, and determines and outputs an object tracking result of the object according to the observation model.
