IMPLEMENTATION OF IMAGE PROCESSING ALGORITHMS ON FPGA

ABSTRACT This presents the use of a high language programming technique to implement image processing algorithms. FPGA is very instrumental in real time image processing because of the properties it holds. For example, FPGA has a structure that has ability to use temporal and special parallelism. This property is only unique to this kind of gates. Hardware constraints of the machine are another factor to consider because it affects the parallelism. Besides hardware constrains, processing mode is also another factor that affects parallelism. Computer engineers have sometimes been forced to change the settings of the algorithm sine the constraints were so illusive and in compatible. This paper is geared towards dealing with some sets of constraints for different types of image processing. INTRODUCTION Computer scientists have always been challenged in their bid to implement real time image processing on serial processors. These difficulties have always been brought up by image properties such as large data sets, and complex operations that need to be performed on the image. In real time processing, 25 frames are witnessed every second. This alone contributes to redundancy and also adds to the slowing down of processing brought about by overheads of retrieval and storing of picture ingredients. In order to counteract the limitations that come with real time image processing, the use of field programmable gate arrays was discovered. FPGA have as a result brought about better revival in this industry (Hutchings, B. and Villasenor, J. pp. 67-84, Sep 1998). FPGA is an integrated circuit if numerous logic cells that are interconnected together for mutual coordination. Before the invention of FPGA, scientists always used fixed circuit of gates but this has numerous disadvantages in line with rigidity and expense. The coming of FPGA was welcomed with great gratitude and soon, these logic cells

    Since 1940’s, computers have emerged and entered most fields of human activity as tools storage and processing of information. A computer is a data processing machine or, in other words a machine for the manipulate of symbols. These symbols represent information of various kinds like a number or a name. A computer is not an independent problem solver. However, the speed with which it can retrieve and manipulate large volume of data aid in problem solving process.…

    I love to explore philosophical perceptions of mathematical axioms. During my undergraduate study, I sharpened my intuitive intellect contemplating on physical interpretations for signal processing concepts. The challenges posed by biomedical signal processing enticed me to take up my dissertation on retinal image registration. The quest to realize signal processing algorithms in real-time made me understand the power of FPGA. During my graduate, I wish to enhance my knowledge in Image Processing and Biomedical Imaging and sharpen my skills in programming FPGA and embedded systems. This would groom me into a holistic researcher capable of providing end to end technology solutions.…

    A field-programmable gate array (FPGA) is an integrated circuit designed to be configured by a customer or a designer after manufacturing—hence "field-programmable". The FPGA configuration is generally specified using a hardware description language (HDL), similar to that used for an application-specific integrated circuit (ASIC) (circuit diagrams were previously used to specify the configuration, as they were for ASICs, but this is increasingly rare). Contemporary FPGAs have large resources of logic gates and RAM blocks to implement complex digital computations. As FPGA designs employ very fast IOs and bidirectional data buses it becomes a challenge to verify correct timing of valid data within setup time and hold time. Floor planning enables resources allocation within FPGA to meet these time constraints. FPGAs can be used to implement any logical function that an ASIC could perform. The ability to update the functionality after shipping, partial re-configuration of a portion of the design and the low non-recurring engineering costs relative to an ASIC design (notwithstanding the generally higher unit cost), offer advantages for many applications.…

    When getting an image containing human faces, it is always better to do some pre-processing such like removing the noisy backgrounds, clipping to get a proper facial image, and scaling the image to a reasonable size. So far we have been doing the pre-processing by hand because we would otherwise need to implement a face-finding algorithm. Due to time-limitation, we did not study automatic face finder.…

    ABSTRACT The existing system available for fuzzy filters for noise reduction deals with fat-tailed noise like impulse noise and median filter. Only impulse noise reduction uses fuzzy filters. Gaussian noise is not specially concentrated; it does not distinguish local variation due to noise and due to image structure. The proposed system presents a new technique for filtering narrow-tailed and medium narrow-tailed noise by a fuzzy filter. The system first estimates a “fuzzy derivative” in order to be less sensitive to local variations due to image structures such as edges. Second, the membership functions are adapted accordingly to the noise level to perform “fuzzy smoothing.” A new fuzzy filter is presented for the noise reduction of images corrupted with additive noise. The filter consists of two stages. The first stage computes a fuzzy derivative for eight different directions. The second stage uses these fuzzy derivatives to perform fuzzy smoothing by weighting the contributions of neighboring pixel values. Both stages are based on fuzzy rules which make use of membership functions. The filter can be applied iteratively and effectively reduce heavy noise. In particular, the shape of the membership functions is adapted according to the remaining noise level after each iteration, making use of the distribution of the homogeneity in the image. A statistical model for the noise distribution can be incorporated to relate the homogeneity to the adaptation scheme of the membership functions. Experimental results are obtained to show the feasibility of the proposed approach. These results are also compared to other filters by numerical measures and visual inspection. Keywords: AFuzzy sets, Fuzzy filters, Fuzzy smoothing, Fuzzy derivative…
