Segmentation

Segmentation is nothing but segmenting the image into multiple pixel sets. It is meant to change the representation of an image. Segmentation makes analysis more simpler as it gives another simpler view of same image. It involves locating the edges of image, objects or any other contrasting things in an image. The output of segmentation is used immensely in lots of applications. For example in medical imaging, segmentation might give you the tumor cell edge as it has greater contrast compared to the rest of image.

Different types to achieve segmentation are :-
Thresholding
Clustering methods
Compression-based methods
Histogram-based methods
Edge detection
Region growing methods
Split-and-merge methods
Partial differential equation-based methods
Graph partitioning methods
Watershed transformation
Model based segmentation
Multi-scale segmentation
Semi-automatic segmentation
Neural networks segmentation

We will look into each of these methods in seperate posts.

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);         }   ...

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();
