[Sovled] is possible make ImageSearch find NEARLY SAME want find

[Nubie]

Hi! I see have alot methods make Image Search around here. But with my tests, they can't find if target isn't same thing I want find (mean not exaclty). Example if target is bigger or smaller (mean not same resolution) or not same color (mean not same pixel color). Of couse their difference isn't too much

I think this's hard to do

Please share your code, or an example of the target, and what you are trying, so we can see what you're attempting to accomplish. There may be a better way to do it, but without seeing what code you have it is almost impossible to offer suggestions.

xample with 2 images here. just change resolution then Image search can't find

for stable I have try by this: 

here's example code I tried

expandcollapse popup

#include "_ImageSearch_UDF.au3"
#include "_ImageSearch_Tool.au3"
#RequireAdmin

HotKeySet("{Esc}", "_Exit") ; Press ESC for exit
Func _Exit()
    Exit 0
EndFunc   ;==>_Exit

Global Const $Ask_On_Found = 0
Global Const $Mouse_Move_On_Found = 1
Global Const $Mouse_Click_On_Found = 0

Global Const $iSleep_Time=500

Global $sCount = 0, $_Image_1 = @ScriptDir & "\example.bmp"

; First, use this function to create a file bmp, maybe a desktop icon for example')
MsgBox(64 + 262144, 'ImageSearch', 'At first, create a file bmp,' & @CRLF & 'photos that will search on the screen!')
_ImageSearch_Create_BMP($_Image_1)

ConsoleWrite("! Search for images: " & $_Image_1 & @CRLF & '! Searching on the screen ...' & @CRLF)

While 1
    ToolTip('(Press ESC for EXIT) Searching ...', 1, 1)
    Sleep($iSleep_Time)
    $sCount += 1
    Local $return = _ImageSearch($_Image_1)
    If $return[0] = 1 Then
        ConsoleWrite('- [' & $sCount & '] Image found:' & " X=" & $return[1] & " Y=" & $return[2] & @CRLF)
        If $Mouse_Move_On_Found Then
            MouseMove($return[1], $return[2])
            Sleep($iSleep_Time)
        EndIf
        If $Mouse_Click_On_Found Then MouseClick("left", $return[1], $return[2])
        ToolTip('(Press ESC for EXIT) - [' & $sCount & "] Image found:" &  " X=" & $return[1] & " Y=" & $return[2], 1, 1)
        If $Ask_On_Found Then
            Local $ask = MsgBox(6 + 262144, 'Success [' & $sCount & ']', 'Image found:' & " X=" & $return[1] & " Y=" & $return[2])
            If $ask = 2 Or $ask = 3 Or $ask = 5 Or $ask = 7 Then Exit ;No, Abort, Cancel, and Ignore
            If $ask = 10 Then _ImageSearch_Create_BMP($_Image_1) ; Continue       ;Try Again
        EndIf
    EndIf
    Sleep(200)
WEnd

disable _ImageSearch_Create_BMP if don't want capture anymore

For the difference of pixel color, you could try using Tolerance parameters of the Image search function.  Be aware that if you have a large Tolerance, you may get false positive.

For the difference in size, you may use GDI+ and reduce the size of the searched image pixel by pixel until you find it.

However there might a better solution than Image Searching if you could tell us what application your are trying to automate.

Thanks your suggestion, I'll try it

I have try make a simple tool detect images in web browser. Something like as "tadah, found you". But I'm surprise it's not work if I change other web browser or change web zoom

You do know that there is some UDF that could do what you are after (IE for Internet Explorer or WebDriver for Chrome and FireFox).  Instead of searching for image, you could way more easily search for tags (ex : img tags).  I would highly recommend that you take a closer look at either one of them.

Thanks for suggestion the method, but I'm only want about Image Search

Ok here's my test

#include <GDIPlus.au3>
#Include <ScreenCapture.au3>
#Include <Array.au3>
#Include <findBMP.au3>

Func _CsvToArray($sSource)
    Local $aLines = StringSplit(StringStripWS($sSource, 2), @CRLF, 1)
    Local $arr[$aLines[0]][100], $iMaxCol = 0, $a, $i, $x
    For $i = 1 To $aLines[0]
        $a = StringSplit($aLines[$i], ",")
        If $a[0] > $iMaxCol Then $iMaxCol = $a[0]
        For $x = 1 To $a[0]
            $arr[$i - 1][$x - 1] = $a[$x]
        Next
    Next
    ReDim $arr[$aLines[0]][$iMaxCol]
    Return $arr
EndFunc   ;==>_CsvToArray

$img1 = FileOpenDialog("Main image", @ScriptDir & "\", "Images (*.jpg;*.bmp;*.png;*.gif)", 1)
$img2 = FileOpenDialog("Sub image", @ScriptDir & "\", "Images (*.jpg;*.bmp;*.png;*.gif)", 1)
_GDIPlus_Startup()
$tResult = findBMP($img1, $img2, 1)
$test = _CsvToArray($tResult)
_GDIPlus_ImageDispose($img1)
_GDIPlus_ImageDispose($img2)
_ArrayDisplay($test)
_GDIPlus_Shutdown()

get findBMP from this for make compare images, just little edit for use _CsvToArray

All image have same size and resolution, tried with GrayScale for bypass pixelcolor

Use button A find button A -> True

Use Button B find all Button A -> False

What I want: use button B find all button A -> True

Ok I found a method can sovle my problem, just need add _GDIPlus_BitmapCloneArea to images before compare

Somethings like as this

_GDIPlus_BitmapCloneArea(Bitmap, 0 ,0 , $W, $H, $GDIP_PXF01INDEXED)

Thanks all, can close this topic
