Project 3: Feature Detection

Program Data Classes and Menu Specifications

(you are required to use these names and structures). NOTE: you may choose to add more elements to these classes....they are not necessarily complete but, contain some beginning ideas to get you started and keep you structurd.

FeatureDetectionProgram Name of class that is the main program for Feature Extraction

Menus of FeatureDetectionProgram File->Open: opens image to be processed. Loads data into class ActiveImage (see Project 2 specifications) File->Save As: saves the current image into a user specified location (see Project 2 work you did) File->Exit: exits the program Process->Feature Detect: runs the blob detection and then the approriate feature detection algorithms (5) on each blob producing BlobList which is vectors containing instances of Blob. Also, saves Blob.xml XML file List->Blobs : displays BlobList in a nice format in a window (scrollable) in the program

CancerAnalysis Class Psuedocode This is a class that contains the BlobList and references to the Image , etc.      class CancerAnalysis{ ImageClass image; //pointer to the Image being processed Vector BlobList;   //vector containing instances of Blob classit       }

Blob Class Psuedocode        class Blob { int ID; //unique ID indicating this blob Location location; //indicates location Area area; //indicates area feature encompasses Feature1 f1; Feature2 f2; Feature3 f3; Feature4 f5;        }

Feature Class Psuedocode      class Feature { String name; // descriptive name (i.e. texture Location location; //indicates location Area area; //indicates area feature encompasses int certainty; //number from 0 to 100 float importance; //indicates importance from 0 to 1.0     //method to return XML formated information: void to_XML(int i){      String s = "<feature" + i + ">";       //you finish the rest to produce xml as described previous...       //this method only returns name, location, area,certainty, importance }   //method to return String formated information: void to_String(int i){      String s = "Feature " + i + ": " + this.description;       //you finish the rest to produce nice string for display in program...       //this method only returns name, location, area,certainty, importance }   }

Feature1 Class Psuedocode (will have similar for Feature2,Feature3,Feature4 and Feature5)      class Feature1 extends Feature { //now add your own pieces of info that describes THIS feature- // i.e info1,info2, info3 you saw above in the XML ........ //constructor Feature1() {      this.description="XXXXX";// you fill in      //whatever else you need in your constructor } //method to return XML formated information.. //return as a string to print out or use javax.xml String to_XML(){     super.to_XML(1); //calls parent method     //you create XML for YOUR feature 1 } //method to return String formated information: String to_String(){     super.to_String(1); //calls parent method     //you create String for YOUR feature 1 } //other methods you need???      }

Location Class Psuedocode      class Location { Point Start, End; //may have a start location and end location Point Center; //may have a center location void setStart(int row, int col) {           this.Start.x = row;           this.Start.y = col; } void setEnd(int row, int col) {           this.End.x = row;           this.End.y = col; } void setCenter(int row, int col) {           this.Center.x = row;           this.Center.y = col; } //add methods as you wish like get*() methods       }

Area Class Psuedocode      class Area { Point UpperLeft, LowerRight; //locations of bounding box int width, left; //dimensions of bounding box Vector Pixels; //create vector of Point object that are                        //given array of Point objects representing pixels Point.x = row, //Point.y=column in this area set them in Pixels array setPixels(Point PointArray){         for(int i=0; i<PointArray.size(); i++)              this.Pixels.add(PointArray[i]); }

Note: reuse ImageClass you created in Project 2. IMPORTANT: add 2 methods to the ImageClass you created called //if using ROI - then add location and dimensions of the ROI here //method to return XML formated information.. //return as a string to print out or use javax.xml String to_XML() {         /*compose string that looks like      <image filename="XXX">      XXX here is the input filename         <width>WWW</width>    WWW is width in pixels         <height>HHH</height>    HHH is height in pixels       </image>       */  } String to_String() {      ///your code to return image info in a formatted string }

FeatureDetectN class Psuedocode (will have FeatureDetect1, FeatureDetect2, FeatureDetect3, FeatureDetect4, and FeatureDetect5) //THIS is for blob-specific cancer detection (i.e. for sure the Masses case) class FeatureDetect1 { Feature1 f1; //vector of Feature1 instances //your algorithm goes here Feature1 detect(CancerAnalysis c, Blob b){      f1 = new Feature1(".....");       //your algorithm goes here     return f1; }     }
