Abstract

In this study, we have aimed to program image processing program about remote sensing, for programming the image processing methods, a preresearch is necessarily about subject of image processing. After my researching I saw that digital image proccesing with computer is very wide subject. Approximately, DIP is used in every engineering. Digital image processing is used in following; a) archive old books at libraries b) to convert from image of graphics sheets to digital values. c) in medical areas. d) in remote sensing e) military f) Translating the language from sound wave data to text file or sounding g) Industrial In this study, Once general laws of image proccesing are described. Cases of image proccesing are like as follows; - The producing the natural image - Histogram production - Geometric Calibration - Histogram equalization - Contrast stretch - Density slicing - Noise filtering - Classification - Multi-spectral classification - image rectification - producing the GIS files. - Data Compressing. Fundamental of image proccesing are widely explained at the following as Turkish Language. CTT data format is explained. Cases of General CTT formats described as follows; JSC Header (3060 Byte ), Landsat Header (1440 Byte), Geaometric Transformation (2700 Byte),

In this study, we have aimed to program image processing program about remote sensing, for programming the image processing methods, a preresearch is necessarily about subject of image processing.

Cases of image proccesing are like as follows; - The producing the natural image - Histogram production - Geometric Calibration - Histogram equalization - Contrast stretch - Density slicing - Noise filtering - Classification - Multi-spectral classification - image rectification - producing the GIS files. - Data Compressing. Fundamental of image proccesing are widely explained at the following as Turkish Language. CTT data format is explained. Cases of General CTT formats described as follows; JSC Header (3060 Byte ), Landsat Header (1440 Byte), Geaometric Transformation (2700 Byte), VIII Radiometric Calibrations band4 (1620 Byte) Radiometric Calibrations bands (1620 Byte) Radiometric Calibrations bando (1620 Byte) Radiometric Calibrations band7 (1620 Byte) Radiometric Calibrations band8 (1620 Byte) Video records, each of the records length is 3780 Byte. There are three records format for the video data. -BSQ (=band Sequantial) -BIL (=band Interleaved by line) -BIP (= Band interleaved by piksel) These formats are used on the image processing program. I programmed on the IBM PC AT compatible computer with DOS operating system. It has SVGA Graphic card. And I used EMS (Expanded memory manager Driver),the source programme is Compiled by Borland C++ 3.01 compiler. Graphics Card is drived as resolution (1024x768) with 256 colors Memory of Graphics card must be 1MB. Microsoft's "Himem.sys" and "emm386.exe" programmes are used as EMS drivers. All of data are loaded to EMS space. Data have been pushed to EMS or poped from EMS. EMS usage is automatic selected, every size of memory is validate. MSS Landsat's data is used as sample data. - Data of Landsat Channel 1 is Blue spectrum. - Data of Landsat Channel 2 is green spectrum. - Data of Landsat Channel 3 is red spectrum. After, according to RGB density, Normal image is displayed. Valid commands in the this program is at the following; zoome, zoomw, pan, redraw, els, palette, stat, band, sinif, sinifprt, load and quit. Zoome, all of the image is displayed on the screen with command. It no have subcommand or subselection. Zoomw, image that the inside of rectangle is zoomed on full-screen. Sensitiving of image on the screen is easily. There are two prompts "First Corner:" and "Other Corner:" Pan, Screen area is replaced on the image area by screen coordinates are changed. by this command. There are two prompts "From Point:" and "To Point". Redraw, the screen is cleared and the image is redisplayed. Displayed data read from expanded memory. Therefore data very speedly displayed. ix Cls, this command clear the screen viewport. Palette, base colors ratio is arranged and visible image that on the screen is uptaded according to new ratio. Comma delimited three data are entered for red, green and blue. Band, current band is selected for the displaying. Range of value is between 1-3. Stat, statistics value of the every channel data are calculated. ( mean value, standart deviation..). after these values are saved as a text file on the fixed disk, or printed. Sinif, this command make unsupervised classification (clustering). Maximum cluster value is 256. Center of channel values are calculated. And classified image is saved on the fixeddisk. Sinifprt, Values calculated by sinif command are saved on the hard- disk. There are printed sample data at the end of this book. Load, this command read from file of ERDAS with ".Ian" or ".gis" extensions, and load to EMS memory. Quit, program is terminated, and returned to DOS system. SVGA 1MB card, minimum 4MB ram, mouse and 120MB harddisk are necessary to run for program.And EMS, mouse and "SVGA256.BGI" drivers are necessary Current diagrams and algoritms of this program are widely explained as tukish. This program is argonomic for user, with Pop-up and pull down menus.
