8 Image Filtering Almost all PxVision function, works with image in black and white that are transformed from a color image by filtering process. In this chapter is explained the various effects all filters on an image.

The goal is to transform a COLOR image in a BLACK/WHITE image with defined contours.

Does not exist a specific rule of filtering, because the result depend from many factors (Quality of image, ambient light etc.). However the BINARY THRESHOLD gives almost always good results.

Button allows to reset the filter parameters by default

ORIGINAL IMAGE IN GRAY MODE FILTERING IMAGE BLACK/WHITE

The filters are in 3 tables

22

PXVISION BROWSER

8.1 Binary Threshold Is the main filter, it allows to set a Binary threshold on image, therefore the values above or below the threshold will be or BLACK or WHITE. This cause that the image will be contrasted and clear, and the functions can work optimally. Normally this filter isn’t combined with others filter but is in any case possible.

This filter can work on image Gray or color . However the best results are with Gray image

Treshold Threshold type

OFF None

0 Binary Threshold. The values of gray image less than Tl are converted in the Th value. The values greater or equal Tl are converted in BLACK value (0)

Image with Tl=116 Th=255

23

PXVISION BROWSER

1 Inverted Binary Threshold. Like Type 0 but are inverted BLACK and WHITE

Image with Tl=116 Th=255

2 Binary Threshold Fixed. The Tl value isn’t considered because is used a Fixed level value

Image with Th=255

3 Binary Threshold to Zero. The values less Tl are converted in BLACK (0) Th isn’t used

Image with Th=158

24

PXVISION BROWSER

4 Binary Threshold to Zero Inverted. The values less Tl are converted in WHITE (255) Th isn’t used

Image with Th=158

5 Binary Threshold Triangular. Is choosen a special algorithm for calculate the Tl parameter Image with Th=255

6 Binary Threshold Truncated. If the value is greater to Tl the value is converted in Tl. Th isn’t used

Image with Tl=96

25

PXVISION BROWSER

7-8 Gaussian Adaptive Threshold. All three parameters are activated Th,Tl,P1. A special algorithm search the contours of image

Image with Tl=254 – Th=18 – P1=9

9-10 Gaussian Adaptive Threshold. All three parameters are activated Th,Tl,P1. A special algorithm search the contours of image

Image with Tl=254 – Th=18 – P1=9

26

PXVISION BROWSER

8.2 Color Threshold RGB or HSV Is possible define the Binary threshold in the color models RGB or HSV. The image will be filter by the threshold color set. The results for RGB or HSV are the same, only the color model is different. Origina image

The Th HSV

By button acquire a “Rectangular area” that contains the color to filtering.

All parameters are set automatically.

The final result of filtering will be the following

27

PXVISION BROWSER

For set manually the values: move by mouse the bars Min Max

28

PXVISION BROWSER

8.3 Blur Filters Could be a paradox, but the images blur makes the contours more visible. The blur eliminate the noise of an image. The Blur filters are present in the table FILTER and they are GAUSSIAN, BLUR, MEDIAN, EROSION, DILATATION. The Blur Filters can combined

Image Without Blur Border aren’t defined cause noise

Image With Blur Border are good defined

29

PXVISION BROWSER

GAUSSIAN GAUSSIAN.

BLUR BLUR.

MEDIAN MEDIAN BLUR.

EROSION EROSION (Normally combined with DILITATION).

EROSION Type Erosion Type

EROSION Cp If Enabled will made EROSION/DILATATION of same value

DILATATION DILITATION (Normally combined with EROSION).

DILATATION Type Dilatation Type

DILATATION Cp If Enabled will made DILATATION/EROSION of same value

MORPHO MORPHOLOGY filter with parameters M. Size and M. Iterat.

30

PXVISION BROWSER

8.4 Filters for find contours These filters find the contours of image. LAPLACIAN and CANNY (C1 C2). They could be combined with others blur filters and Binary Threshold

LAPLACIAN LAPLACE algorithm

Threshold=OFF – GAUSSIAN=7 – LAPLACIAN=3

CANNY (C1 -C2) CANNY algorithm

Threshold=OFF – GAUSSIAN=5 – BLUR=6 – C1=120 – C2=81

31

PXVISION BROWSER

8.5 Brightness and Contrast filters These filters are similar to BRIGHTNESS and CONTRAST of the CAMERA Are in the table FILTER 2, GAMMA, ALPHA, BETA, Eq. Hist. Original Image Image with GAMMA=3.5 – ALPHA=1.8 – BETA=-4

32

PXVISION BROWSER

9 Region and Border image In some situation is better analyze an image portion instead of the whole image, that allow to exclude all pixels out side the Region. The region is defined by table REGION and works only if the function is enabled to use the Region (not all functions are enabled to use the region). The BORDER can define a rectangular Border with specific color and dimensions around the image, this allows to separate the image from the camera limits Up, Down, Left and Right.

9.1 Capture a Region For capture a REGION, is necessary to use a function enabled for the region use Ex: Marker Detection -> Marker Circular Start the images acquisition by START TEST for capture an image frame and press Stop Test (if Multi Frame is checked) Open REGION tab

The REGION is active if W (Width) parameter is different to -1 By TextBox X ,Y, W, H is possible to insert the values (Pixel). After insert the values press button SET REGION for REGION activation. For disable the region insert W=-1 (and press Set Region) or press button DISABLE REGION Is possible set a REGION by MOUSE. Press button By Mouse, and after click and hold with Left mouse button in an corner of desired region, drag the mouse pointer until desired region (a rectangular image will be showed) and release the left button. During the images acquisition, if a region is activated, a rectangular YELLOW border will be showed

X,Y

W (Width)

H (Height)

33

PXVISION BROWSER

9.2 Border Definition The BORDERS are defined as RECTANGULAR contour of image inside the REGION (if it is activated). Normally the BORDERS have to of Color how the background, that allows to separate the image with background. The use of Borders is useful when some particulars of image are outside the camera limits.

The BORDER definition separates the objects from camera limits

For define a BORDER set the parameters LEFT, RIGHT, TOP, BOTTOM they are the width in PIXEL of the BORDER in the four sides. The BORDER color is defined by parameters R,G,B (from 0 to 255) BLACK 0,0,0 – WHITE 255,255,255 Is important to set the color of border like background color, for see the background color use camera setting and capture an image without filters (real image), move the mouse pointer on the background an read the RGB values in the window:

The values read are the color of border The BORDER is disabled with LEFT = -1

In the image, the Black Lines are outside the left and right limits of camera. In this case some algorithms could not work good
