This paper describes Parallel Spectral Deconvolution (PSD) Java software for image deblurring. A key component of the software, JTransforms, is the first, open source, multithreaded FFT library written in pure Java. Benchmarks show that JTransforms is competitive with current C implementations, including the well-known FFTW package. Image deblurring examples, including performance comparisons with existing software, are also given.
