Extract-text-from-image

Image processing and extracting text from gray scale image (for fpga course project at university)

it is implemented and designed for virtex5-XC5VLX110T-FF1136 fpga board .

Input

make .coe file from gray scale image:

In image_to_coe.py just pass image directory in to convert function and run it .

One byte of data is stored for each image .

Implementation :

we implement a single port RAM using the Block Memory Generator ip core .

Images are loaded and read in readMemory.v and connect to logic using intermediate.v module .

Logic

logic.v is a Verilog code receives the image from the input and separates the text from image and delivers it to the output in one clock ( combinational ).

Output

logic output is connected to VGA_Controller.v in topModule.v .

VGA_Controller outputs used in .ucf file .
