INTRODUCTION

ABSTRACTABST

Our project topic is “IMAGE PROCESSING TECHNIQUES”. It is a desktop based application. This project aims at creating various effects for processing an image of format .jpg. Our objective is to give a clear outlook about the various operations or effects that can give to an image to change its original look. We select this topic as our project by acquiring motivations from various existing softwares such as Windows Picture Management likewise…We use java net beans as a supporting software while commencing this project. The pixel grabber function in java helps to grab each image into its pixel level.

LANGUAGE DESCRIPTION

JAVA

JAVA

Java is the first and foremost an object-oriented programming language. Java is a programming language originally developed by James Gosling at Sun Microsystems. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities. Java applications are typically compiled to byte code (class file) that can run on any Java Virtual Machine (JVM) regardless of computer architecture.

Primary characteristics of Java:

The ease with which you can transition to Java from C or C++ and Java’s object-oriented capabilities are not only the advantages, but also Java has some

Other features such as:

•Simple •Object-oriented•Platform-independent•Robust•Secure•Distributed •Dynamic•Portable•Multithreaded

NET BEANS

Net Beans refers to both a platform framework for Java desktop applications, and an integrated development environment (IDE) for developing with Java, JavaScript, PHP etc.The Net Beans IDE is written in Java and runs everywhere where a JVM is installed, including Windows, Mac OS, Linux, and Solaris. A JDK is required for Java development functionality, but is not required for development in other programming languages. Net Beans IDE 6.5, released in November 2008

Features•CSS editor: with syntax highlighting, code completion and preview. •HTML editor with auto completion, syntax highlighting, basic drag and drop CVS, Subversion, •Mercurial integration: I use it e.g. to synchronize the chapters of my current book with Oreille.•JavaScript editor / debug support •The ability to browse the file system and edit files. NB can be used as a generic editor. •Services: Great database viewer with paging, inline editing etc. •UML support (additional 7MB plug-in): really good tool for creating overview diagrams etc.

OPEN MENU:

LOADING AND SAVING AN IMAGE 

When you select either open or save menu from the file menu the corresponding dialogue box will appear. We can browse to the decide picture using this dialogue box. After selecting the picture we can insert that into our work area by double clicking the picture or clicking the open button in the dialogue box. In the save dialogue box browse to the folder where we want to save our file name it and click save button. Thus it will save in the corresponding folder.

EFFECTS:

FGGGGGGGGREYIMAGE: Grayscale or grayscale digital image is an image in which the value of each pixel is a single sample, that is, it carries only intensity information. Images of this sort, also known as black-and-white, are composed exclusively of shades of gray, varying from black at the weakest intensity to white at the strongest.

GREYIMAGE:

EDGE DETECTION: This filter detects the edges in a filter. For each pixel, It looks a each channel, finds the local gradient and replaces the channel by a value determined by the gradient. Edges become white while flat areas become black. Edge detection filters work essentially by looking for

contrast in an image. 

EDGEDETECT:

INVERT : This filter will invert the alpha channel of an image. This is not normally terribly useful, but has its uses on accession. There are no parameters to this filter. This filter will invert all the pixels in an image, converting it into its photographic negative. It's pretty much the simplest possible filter: To invert a pixel we, simply subtract each color component from 255. It takes apart the red, green, and blue channels and then inverts them by subtracting them from 255.These inverted values are packed back into a pixel value and returned.

INVERT:

Red Eye ViewColor filters are sometimes classified according to their type of spectral absorption.The most useful thing to do with this filter is to set two colors to -255 in order to strip them and see one color component of an image. Every color has an implicit alpha value of 1.0 or an explicit one provided in the constructor.

Red Eye View

Brightness

Brightness makes the image lighter or darker .It Increase or decrease the brightness of pixels. Low brightness will result in dark tones while high brightness will result in lighter, pastel tones.

Horizontal Mirror Placing the edge of a mirror on the y-axis will form a reflection in the y-axis.This function is used to flip the source image from left to right.

Horizontal Mirror

Vertical StretchA vertical stretching is the stretching of the graph away from the y-axis.

Vertical Stretch

wrrrrrrrrrr ShearShearing slides one edge of an image along the X or Y axis, creating a parallelogram. An X direction shear slides an edge along the X axis, while a Y direction shear slides an edge along the Y axis.Here the x shear is take place.

Shear

C - CropCrop means cutting images down to size.

The size of the displayed image has not been effected by the “crop" operation. The actual image itself has been cropped, but the canvas on which the image is displayed is still the same size as the original canvas.

Green Eye ViewColor filters are sometimes classified according to their type of spectral absorption:

The most useful thing to do with this filter is to set two colors to -255 in order to strip them and see one color component of an image.

The color class is used encapsulate colors in the default RGB color space or colors in arbitrary color spaces identified by a color space.

RGB use 8 bit color representation.

Working Process:

Here for green filter, keep the green component as it is 225 and just subtract 255 from the red component & blue component.

For green filter set RGB values as (1,255,1).

RGB color with the specified red, green & blue values in the range (0 - 255).

Green Eye View

Blur

Blur is often used to reduce within an image or to produce a less pixilated image.Blur method is opposite of sharpen.Blur method are based on low pass filter.Blur other wise know as SMOOTH.

Working Process:

Blur is also usually based on a single value presenting the image, such as the average value of the image or the middle value.

To produce this blur effect, the filter takes the average of the present pixel value and the value of adjacent pixels and set the present pixel to that average value.

Each pixel in the source image gets spread over and mixed into surrounding pixels.

Blur

Vertical Mirror Vertical Mirror is also referred to as creating a mirror of a image & this function is used to flip the source image from top to bottom.

The reflection transformation produces a mirror image of the object with respect to a specified axis, point or line.

If either the x-axis or y-axis is treated as a mirror, the object has a mirror image or reflection.

Since the reflection of an object is located at the same distance from the mirror axis the original image from the axis.

This reflection is also know as GLIDE REFLECTION

Working Process:The reflection operator geometrically transforms an image such that image element i.e. pixel values, located at position (x1,y1) in an original image are reflected about a user-specified image axis or image point into a new position (x2,y2) in a corresponding output image.

A glide reflection is a transformation in the plane that is the composition of a line reflection and a translation through a line (a vector) parallel to that line of reflection.

Vertical Mirror

ZoomZoom is a transformation that effectively scales down or blows up a pixel map or a position of it with the instruction.

Zoom can be classified into two: ZOOM INZOOM OUT

Working Process:To resizing an image arbitrarily the easiest way to do it is to calculate a factor for the difference between the source and destination in both x and y axis, then use that factor of figures out which pixel on the source image maps to the color being placed on the destination image.

The modified (zoomed image) should be the same size as the original image; in a zoomed image the specified portion of the original image now fills the entire image window.

Subjective quality of an image indicating clear or distinct reproduction of detail: associated with resolution and contrast. Edge enhancement is an extremely common technique used to make images appear sharper.To sharpen the image is very similar to finding edges, add the original image, and the image after the edge detection to each other, and the result will be a new image where the edges are enhanced, making it look sharper.ConvolveOP convolution filter that applies a given kernel operator to the image data for effect such as sharpening.

We can do the same trick to make light rays appear to come out of an object, only this time making the shadow color white and using a zoom blur instead of the ordinary blur, then adding the result on top of the original.

Also custom effect reduces the clarity of an image.

Also custom effect change the order of pixel elements and effect is distortion

Transform attribute in the Graphics2D context to move, rotate, scale, and shear graphics primitives when they are rendered.

The transform attribute is defined by an instance of the AffineTransform class. An affine transform is a transformation such as translate, rotate, scale, or shear in which parallel lines remain parallel even after being transformed.

The rotate operation rotates an image about a given point by a given angle.
