Box Blur

As i promised in my earlier posts that we will return to Blurring Image concepts, we are back.
In this post, i will try to explain Box Blur.

Box Blur is basically an image filter which gets created by taking average values of its neighboring image. Since taking average value of pixels is simple, the algorithm can be implemented quite easily.

One of the major advantage of Box Blur is that if applied repeatedly it approximates to Gaussian Kernel.

Mini Project for Image Processing Beginners

A short project for Engineering graduates. Take an MRI Scanned image or a X-Ray image of healthy person as well as a patient and compare the pixel values, edges etc. This will help you understand the general values of a healthy body. Using that as mean or median, try to create an diagnoses software using these images as input. I will add the sample code or algorithm for your reference. So keep checking the blog for more.

Program to convert image byte array to PDF

Simple sample program to convert image byte array to PDF         //input path. path where byte array is saved         String pathOfByteArrayFile = "/home/inputByteArray.txt";         //output path. path where rendered you need to save . Output PDF should render properly         String outputPDFPath = "/home/output.pdf";         try         {             File file = new File(pathOfByteArrayFile);             FileOutputStream fout = new FileOutputStream(outputPDFPath);             byte[] bArray = Base64.decode(FileUtils.readFileToByteArray(file));             fout.write(bArray);             fout.close();             assertFalse(false);         }         catch (Exception e)         {             //your logic for failure         }

Program to convert base64 to Image and vice versa

Code snippet: This method decodes the base64 string into the bytes and converts it into an image .      * Note: this method expects input to be an encoded Image in base64 format. It can't work with other other files encoded in base64 format ByteArrayInputStream bis = new ByteArrayInputStream(Base64.getDecoder().decode(base64data)); BufferedImage img = ImageIO.read(bis); bis.close(); This method encodes the PNG image to base64 format ByteArrayOutputStream output = new ByteArrayOutputStream(); ImageIO.write(image, "PNG", output); String encodedString = Base64.getEncoder().encodeToString(output.toByteArray()); output.close();
