This paper presents a novel error-free (infinite-precision) architecture for the fast implementation of both 2-D Discrete Cosine Transform and Inverse DCT. The architecture uses a new algebraic integer quantization of a 1-D radix-8 DCT that allows the separable computation of a 2-D DCT without any intermediate number representation conversions. This is a(More)
The paper presents a lifting based algorithm to compute Daubechies-4 (D4) and Daubechies-6 (D6) Wavelet Transforms using a novel algebraic integer quantization (AIQ) technique. The complex transform filter coefficients are first mapped error-freely by algebraic integers, and then quantized using subband coding algorithm. The performance of the scheme is(More)
This paper describes the development of a prototype of a low-cost digital fluorescent microscope built from commercial off-the-shelf (COTS) components. The prototype was tested to detect malignant tumor cells taken from a living organism in a preclinical setting. This experiment was accomplished by using Alexa Fluor 488 conjugate dye attached to the cancer(More)

This paper presents a novel error-free (infinite-precision) architecture for the fast implementation of both 8/spl times/8 2D discrete cosine transform and inverse DCT. The architecture uses a new algebraic integer quantization of a 1D radix-8 DCT that allows the separable computation of a 2D 8/spl times/8 DCT without any intermediate number representation(More)
