In this paper, a new adaptive vector directional distance filter (AVDDF) is proposed. The AVDDF filter is developed to remove the 'salt and papper' impulsive noise in color images. This algorithm consists in first step to detect pixels that are likely to have been contaminated with noise by using a threshold value. In second step, after recognizing the corrupted pixels, the smallest angular-magnitude distance is used to replace the noisy pixels. The proposed filter is tested with several standard color images which are contaminated with various levels of 'salt and pepper' impulsive noise (3%, 5%, 10%, 20% and 30%). The performance of the proposed filter is measured with peak signal-to-noise ratio (PSNR) and normalized color difference (NCD). The simulation results show that the proposed filter permits to ameliorate the performance of the classic vector directional distance filter (VDDF). Indeed, it provides an improvement by an average of 5% and 26% in the PSNR and NCD relative to the VDDF filter, respectively, with a small increase in the execution time by 6%. Besides, the AVDDF filter allows also an enhancement by an average of 2% and 14% in the PSNR and NCD relative to adaptive vector median filter (AVMF), respectively.

“…Many nonlinear filters have been proposed in the literature such as the Vector Median Filter (VMF) [7], the Adaptive Vector Median Filter (AVMF) [8], the Vector Median Rational Hybrid Filter (VMRHF) [9], etc. Many researchers have noted the time consuming and the high complexity of non-linear filters [10,11]. However, to reduce this complexity, researchers have adopted hardware acceleration as a solution.…”

In this paper, a software/hardware High-level Synthesis (HLS) design is proposed to compute the Adaptive Vector Median Filter (AVMF) in realtime. In fact, this filter is known by its excellent impulsive noise suppression and chromaticity conservation. The software (SW) study of this filter demonstrates that its implementation is too complex. The purpose of this work is to study the impact of using an HLS tool to design ideal floating-point and optimized fixed-point hardware (HW) architectures for the AVMF filter using square root function (ideal HW) and ROM memory (optimized HW), respectively, to select the best HLS architectures and to design an efficient HLS software/hardware (SW/HW) embedded AVMF design to achieve a trade-off between the processing time, power consumption and hardware cost. For that purpose, some approximations using ROM memory were proposed to perform the square root and develop a fixed-point AVMF algorithm. After that, the best solution generated for each HLS design was integrated in the SW/HW environment and evaluated under ZC702 FPGA platform. The experimental results showed a reduction of about 65% and 98% in both the power consumption and processing time for the ideal SW/HW implementation relative to the ideal SW implementation for an AVMF filter with the same image quality, respectively. Moreover, the power consumption and processing time of the optimized SW/HW are 70% and 97% less than the optimized SW implementation, respectively. In addition, the Look Up Table (LUTs) percentage, power consumption and processing time used by the optimized SW/HW design are improved by nearly 45%, 18% and 61% compared the ideal SW/HW design, respectively, with slight decrease in the image quality.
