Conventional SIMD image processors are very effective for early visual processing because of their parallelism. However, in performing more advanced processing, they exhibit some problems, such as poor performance in global operations and a tradeoff between flexibility of processing and the number of pixels. This paper shows a new architecture and sample(More)
This paper describes a new vision chip architecture for high-speed target tracking. The processing speed and the number of pixels are improved by hardware implementation of a special algorithm which utilizes a property of high-speed vision and introduction of bit-serial and cumulative summation circuits. As a result, 18 objects in a 128 128 image can be(More)
This paper describes a vision chip architecture for high-speed vision systems that we propose. The chip has general-purpose processing elements (PEs) in a massively parallel architecture, with each PE directly connected to photo-detectors. Control programs allow various visual processing applications and algorithms to be implemented. A sampling rate of 1ms(More)
We propose a variant of the multi-touch display technology that introduces an original way of manipulating three-dimensional data. The underlying metaphor is that of a deformable screen that acts as a boundary surface between the real and the virtual worlds. By doing so, the interface can create the illusion of continuity between the userpsilas real space(More)
In this paper, we propose an interaction system which displays see-through images on the mobile display and that allows a user to interact with virtual objects overlaid on the see-through image using the user's hand. In this system, the camera which tracks the user's viewpoint is attached to the front of the mobile display and the depth camera which(More)
We describe a high-speed vision system for real-time applications, which is capable of processing visual information at a frame rate of 1 kfps, including both imaging and processing. Our system performs moment-based analysis of numerous objects. Moments are useful values providing information about geometric features and invariant features with respect to(More)
We propose a new user interface system for mobile devices. By using augmented reality (AR) technology, the system overlays virtual objects on real images captured by a camera attached to the back of a mobile device, and the user can operate the mobile device by manipulating the virtual objects with his/her hand in the space behind the mobile device. This(More)
In this paper, we propose a novel method of hand recognition for remote mid-air pointing operation. In the proposed method, classification scores are calculated in a sliding window for hand postures with different pointing directions. Detection of a pointing hand and estimation of the pointing direction is performed by interpolating the classification(More)
This paper describes real-time shape measurement using a newly developed high-speed vision system. Our proposed measurement system can observe a moving/deforming object at high frame rate and can acquire data in real-time. This is realized by using two-dimensional pattern projection and a high-speed vision system with a massively parallel co-processor for(More)
