  4. 4. ABSTRACTABST Our project topic is “IMAGE PROCESSINGTECHNIQUES”. It is a desktop based application. Thisproject aims at creating various effects for processingan image of format .jpg. Our objective is to give aclear outlook about the various operations or effectsthat can give to an image to change its original look.We select this topic as our project by acquiringmotivations from various existing softwares such asWindows Picture Management likewise…We use javanet beans as a supporting software while commencingthis project. The pixel grabber function in java helps tograb each image into its pixel level.
  5. 5. HARDWARE REQUIREMENTS In order to implement a new system thechoice of a processor with maximum possiblespeed is made there should be sufficientmemory to store data and software tools forefficient processing. Processor : Pentium IV or above Clock Speed : 800 MHz Main Memory : 256 MB RAM Disk Storage : 80 GB or above Monitor : SVGA Color Key Board : 108 Keys Mouse : Logitech Floppy Disk Drive : 3.5 floppy 1.44 MB Compact Disk Drive: 52 x max
  6. 6. SOFTWARE REQUIREMENTSOperating System : Windows 2000 or aboveFront End : Java Net Beans 6.5
  7. 7. LANGUAGE DESCRIPTIONJAVA JAVA Java is the first and foremost an object-orientedprogramming language. Java is a programminglanguage originally developed by James Gosling atSun Microsystems. The language derives much of itssyntax from C and C++ but has a simpler object modeland fewer low-level facilities. Java applications aretypically compiled to byte code (class file) that can runon any Java Virtual Machine (JVM) regardless ofcomputer architecture.
  8. 8. Primary characteristics of Java: The ease with which you can transition to Java fromC or C++ and Java’s object-oriented capabilities arenot only the advantages, but also Java has someOther features such as:•Simple•Object-oriented•Platform-independent•Robust•Secure•Distributed•Dynamic•Portable•Multithreaded
  9. 9. NET BEANSNet Beans refers to both a platform framework forJava desktop applications, and an integrateddevelopment environment (IDE) for developing withJava, JavaScript, PHP etc.The Net Beans IDE iswritten in Java and runs everywhere where a JVM isinstalled, including Windows, Mac OS, Linux, andSolaris. A JDK is required for Java developmentfunctionality, but is not required for development inother programming languages. Net Beans IDE 6.5,released in November 2008
  10. 10. Features•CSS editor: with syntax highlighting, code completionand preview.•HTML editor with auto completion, syntax highlighting,basic drag and drop CVS, Subversion,•Mercurial integration: I use it e.g. to synchronize thechapters of my current book with Oreille.•JavaScript editor / debug support•The ability to browse the file system and edit files. NBcan be used as a generic editor.•Services: Great database viewer with paging, inlineediting etc.•UML support (additional 7MB plug-in): really good toolfor creating overview diagrams etc.

  29. 29. GREYIMAGE: FGGGGGGG Grayscale or grayscale digital image is animage in which the value of each pixel is a singlesample, 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 whiteat the strongest.
  30. 30. GREYIMAGE:
  31. 31. EDGE DETECTION: This filter detects the edges in a filter. For each pixel, Itlooks a each channel, finds the local gradient andreplaces the channel by a value determined by thegradient. Edges become white while flat areas becomeblack. Edge detection filters work essentially by lookingforcontrast in an image .
  32. 32. EDGEDETECT:
  33. 33. INVERT : This filter will invert the alpha channel of an image. This isnot normally terribly useful, but has its uses on accession. Thereare no parameters to this filter. This filter will invert all the pixels inan image, converting it into its photographic negative. Its prettymuch the simplest possible filter: To invert a pixel we, simplysubtract each color component from 255. It takes apart the red,green, and blue channels and then inverts them by subtractingthem from 255.These inverted values are packed back into a pixelvalue and returned.
  34. 34. INVERT:
  35. 35. Horizontal StretchA horizontal stretching is thestretching of the graph away fromthe x-axis.It use affine transformation

  57. 57. Green Eye ViewColor 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.
  58. 58. 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).
  59. 59. Green Eye View
  60. 60. 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.
  61. 61. 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.
  62. 62. Blur
  63. 63. 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
  64. 64. 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.
  65. 65. Vertical Mirror
  66. 66. ZoomZoom 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 INZOOM OUT
  67. 67. Working Process:To resizing an image arbitrarily the easiest way to doit 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.

  74. 74. SharpenSubjective quality of an image indicating clear ordistinct reproduction of detail: associated withresolution and contrast. Edge enhancement is anextremely common technique used to make imagesappear sharper.To sharpen the image is very similar to findingedges, add the original image, and the image afterthe edge detection to each other, and the result willbe a new image where the edges are enhanced,making it look sharper.ConvolveOP convolution filter that applies agiven kernel operator to the image data for effectsuch as sharpening.
