A VLSI array architecture for Hough transform
In this article, an asynchronous array architecture for straight line Hough Transform (HT) is proposed using a scaling free modified CORDIC (CoOrdinate Rotation Digital Computer) unit as a basic Processing Element (PE). It exhibits four-fold angle parallelism by dividing the Hough space into four subspaces to reduce the computation burden to 25% of the conventional requirements. A distributed a...
متن کاملVLSI Implementation of Discrete Wavelet Transform using Systolic Array Architecture
The wavelet transform has itself a useful tool in the field of 1-dimensional and 2-dimensional signal compression systems. Due to the growing importance of this technique, there is an increasing need in many working groups for having a development environment which could be flexible enough and where the performance of a specific architecture could be measured, closer to reality rather than in a...
متن کاملParametrized Architecture for Hough Transform Recursive Evaluation
The Hough Transform (HT) is a useful technique in image segmentation, concretely for geometrical primitive detection. A Convolution-Based Recursive Method (CBRM) is presented for function evaluation. In this generic approach, calculations are carried out by an unique parametric formula which provides all function points by successive iterations. The case of combined trigonometric functions invo...
متن کاملCordic based parallel/pipelined architecture for the Hough transform
We present the design of parallel architectures for the computation of the Hough transform based on application-specific CORDIC processors. The design of the circular CORDIC in rotation mode is simplified by the a priori knowledge of the angles participating in the transform and a high throughput is obtained through a pipelined design combined with the use of redundant arithmetic (carry save ad...
متن کاملA VLSI Architecture for the Discrete Wavelet Transform
This paper gives a summary of the wavelet transform for both continuous and time discrete signals. An algorithm for an effective computation of the DWT, namely the Mallat Algorithm, is described in greater detail. Its implementation with FIR filters can be optimized by applying the lifting scheme. This can extremely reduce the computational complexity. Some possible architectures that map the M...
