    Status: Answered => Open

Winnie Hsu is still having a problem:
The output makes me confused.  Why screenshot Masked matches score
max/min below 0.8, the image is same as  shotMasked. But shotMasked's
score is so higher.

The Output is :
##### searching for: (1536898174.png) original image

found: 1 matches score max/min: 0.7643 / 0.7643

##### searching for: (P(test20180914-1.png) S: 0.7 masked) masked with
other image (image-masked)

found: 1 matches score max/min: 0.9995 / 0.9995

##### searching for:
(P(D:/Sikuli1.1.3/Reports/Screenshot/test20180914.png) S: 0.7 masked)
masked with screen image (image-masked)

found: 1 matches score max/min: 0.7790 / 0.7790
-----------------------------------------------------------------------------------

My Code is as Follows:

some_region = App.focusedWindow()
imgabc = capture(some_region)
screenshotsDir = "D:\Sikuli1.1.3\Reports\Screenshot"
shutil.move(imgabc, os.path.join(screenshotsDir, "test"+ time.strftime('%Y%m%d') +".png"))        
wait(1)  
#baseimg = os.path.join(screenshotsDir, "test"+ time.strftime('%Y%m%d') +".png")
baseimg = os.path.join(screenshotsDir, "test20180914.png")
wait(1)  
shot = "1536898174.png"
shotA = "test20180914-1.png"
# image with black/white parts useable as mask
shotMask = "bbb-1.png"

wait(5)

# Image masked with black/white image shotMask (image-masked)
shotMasked = Pattern("test20180914-1.png").mask(shotMask)
shotMaskedscreen = Pattern(baseimg).mask(shotMask)
# find the search area
# the image shot-tile-small.png must be visible on screen
reg = None
for match in findAllList(shot):
    if reg: reg = reg.union(match)
    else: reg = match
if reg:
    reg = reg.grow(0)
    reg.highlight(2, "green")
else:
    print "search area not visible"
    exit(-1)

# a generalized function for this demonstration
def search(image, descr = ""):
    print "##### searching for: (%s) %s" % (image, descr)
    matches = reg.findAllList(image)
    if len(matches) > 0:
        scoreMax = 0
        scoreMin = 1
        for match in matches:
            match.highlight()
            score = match.getScore()
            if score > scoreMax: 
                scoreMax = score
            if score < scoreMin: 
                scoreMin = score
        print "found: %d matches score max/min: %.4f / %.4f" % (len(matches), scoreMax, scoreMin)
    else:
        print "    found: no matches"
    wait(2)
    highlightOff()

# showcase original image
search(shot, "original image")

# showcase image-masked
search(shotMasked, "masked with other image (image-masked)")
search(shotMaskedscreen, "masked with screen image (image-masked)")
