image algo to vhdl conversion

 I am unable to convert a simple image code into vhdl using hdl coder. Please help

 
FUNCTION:
 
%#codegen
function[a,b]=imate2vhdl(x)
a=imread(x);
b=im2bw(a);

TESTBENCH:

x = 'v.jpg';
[a,b]= imate2vhdl(x);
imshow(b);

The function you wish to generate HDL for contains two function calls (imread and im2bw), and neither function is supported for HDL code generation. imread reads a file from disk and decodes the binary format; in this case, JPEG. I'm not sure what hardware you expect HDL Coder to build for such a function call; in any case, HDL coder does not support it.
The reason that HDL Coder does not support im2bw is that it operates on a frame buffer. The entire image is processed at once, as an image. As written, HDL Coder has no idea even how large the image is.
In general, hardware processing of images or video needs to be performed in a streaming fashion. I could envision remodeling this design so that:
  • The image size is fixed and defined
  • The image is streamed, one pixel at a time, into the hardware design
  • The incoming data stream is processed, pixel by pixel, performing the transform
  • The transformed data is streamed out of the hardware portion back into an image buffer
This of course is one approach. It is so simple because the filter you wish to use is a simple pixel-level filter.

USING MACHINE LEARNING CLASSIFICATION ALGORITHMS FOR DETECTING SPAM AND NON-SPAM EMAILS

    ABSTRACT We know the increasing volume of unwanted volume of emails as spam. As per statistical analysis 40% of all messages are spam which about 15.4 billion email for every day and that cost web clients about $355 million every year. Spammers to use a few dubious techniques to defeat the filtering strategies like utilizing irregular sender addresses or potentially add irregular characters to the start or the finish of the message subject line. A particular calculation is at that point used to take in the order rules from these email messages. Machine learning has been contemplated and there are loads of calculations can be used in email filtering. To classify these mails as spam and non-spam mails implementation of machine learning algorithm  such as KNN, SVM, Bayesian classification  and ANN  to develop better filtering tool.   Contents ABSTRACT 2 1.

Why are Fourier series important? Are there any real life applications of Fourier series?

A  Fourier series  is a way of representing a periodic function as a (possibly infinite) sum of sine and cosine functions. It is analogous to a Taylor series, which represents functions as possibly infinite sums of monomial terms. A sawtooth wave represented by a successively larger sum of trigonometric terms. For functions that are not periodic, the Fourier series is replaced by the Fourier transform. For functions of two variables that are periodic in both variables, the trigonometric basis in the Fourier series is replaced by the spherical harmonics. The Fourier series, as well as its generalizations, are essential throughout the physical sciences since the trigonometric functions are eigenfunctions of the Laplacian, which appears in many physical equations. Real-life applications: Signal Processing . It may be the best application of Fourier analysis. Approximation Theory . We use Fourier series to write a function as a trigonometric polynomial. Control Theory . The F
