A review of HDL-based system for real-time image processing used in tumors screening

The use of hardware description languages to provide digital image processing results is a recent technique that offers a direct connection to reconfigurable hardware implementation. This paper presents a real time system for digital image processing using Verilog hardware description language that can be followed by immediate hardware implementation possibility. The image enhancement algorithms included in the described system were applied to an ultrasound image. The paper focuses on image enhancement methods such as contrast and brightness transformation, inverting and pseudo-coloring images, described and simulated using Verilog hardware description language. With our study we intend to contribute to the diagnoses of invasive and non-invasive methods in pre-operator stage, using modern VLSI technologies with applications in medical imaging.
