There are 5 Geometrical Transform tools,you select these tools on the warping toolbar. Horizontal flip Vertical flip, Flip the image horizontally, along the vertical axis., Flip the image vertically, along the horizontal axis. Image warping menu Zoom Transform,Change image size and position. When the mouse is on the control point, Press mouse left button and move the control point on the adjustment frame, you can change the size of the image. When the mouse is inside the adjustment fram e, keep pressing the left button; you can move the image in different directions. Image Rotate,Rotate tool is used to alter the image angle and position. Using mouse to rotate or move the adjustment frame, you can change the image angle and position. Free Transform,Free Transform used to change the image shape freely. Using mouse to move the control point on the adjustment frame, you can change the shape of the image freely. Net warping can warp the image.,using mouse to move the control point on the net, you Control frame 1.2.2 Gray Value Image Processing a. Invert Inverts the image, converts positive image to negative image,or converts negative image to positive image. 4
b. Grayscale Delete color information of the image, and converts the image to grayscale image. c. Shade Correction Shade correction is used to correct systematic errors in the image brightness, usually caused by uneven illumination of the sample. There are three shade correction methods in the software. Use them to produce different results. d. Field Shade Correction First capture an image under the same illumination condition but without the sample and selects menu item reference image to save it as a reference image. Second capture the image need to correct, and select menu item shade correction, a dialog box will request an reference image, press load button, and slide the slider control button, will produce different correction results. e. Image Smooth ScopeImage Advanced offers the following smooth filters: Average, Median and Low Pass. Average filter smoothes an image by replacing the center pixel in a neighborhood with the average value of the neighborhood. Median filter smoothes an image by modifying pixels that varies significantly from their surroundings. This is accomplished by replacing the center pixel in a neighborhood with the median value of the neighborhood. This filter is particularly effective at removing random spots or points that vary significantly from the background and high-impulse noise from an image. Low Pass filter blurs an image by modifying a pixel value to be more like its neighbors. This eliminates harsh edges by reducing the intensity differences between adjacent pixels. All these filters can be used to blur an image to eliminate details or random image noise. f. Edge detection ScopeImage Advanced offers the following Edge detectors: Roberts, Sobel, Laplacian, Kirsch, Prewitt, Horizontal Edge, Vertical Edge, Upright edge, Down Left Edge. These edge detectors extract and enhance edges and contours in an image by expressing intensity differences between neighboring pixels as an intensity value. Roberts filter highlighted edges against a dark background; Sobel filter is less sensitive to image noise. This generally results in an image with smoother, more pronounced outlines of only the principal edges. The Roberts filter enhances all edges within an image, even those introduced by noise. It highlighted edges against a dark background, and can get good results for binary image. So if your image appears black following a Roberts s filter, use your brightness, contrast to lighten the image and bring out the edge detail. Sobel filter is less sensitive to image noise. This generally results in an image with smoother, more pronounced outlines of only the principal edges. Laplacian results are very similar to those of Hi-Pass. It produces an image with harsh intensity transitions, and results in an image with only edges of high contrast visible. Kirsch, and Prewitt can get thick edges; they work in the way similar to pattern matching process. 5
Horizontal Edge detects horizontal edges, so used it when horizontal features need to be extracted from an image. Vertical Edge extracts vertical edges in an image by highlighting pixels with significant intensity differences from those to the left and right of it. It produces an image with just its vertical edges visible against a flat background. Vertical Edge filtering is used when vertical features need to be extracted from an image. You can select suitable edge detectors for different images. g. Image Arithmetic Image Arithmetic performs logic operations and arithmetic upon the active image, or AOI. Such operations are performed between two images. When you select the arithmetic command, the Image calculation dialog box will be presented. Within this box, select the kind of calculation you want to perform, the input image and out put image you want it to work with.
