python实现根据图标提取分类应用程序实例
本文实例讲述了python实现根据图标提取分类应用程序，分享给大家供大家参考。
具体方法如下：
#!/usr/bin/python
#-*-coding:utf-8-*-
importImage
importwin32ui
importwin32gui
defmake_regalur_image(img,size=(256,256)):
returnimg.resize(size).convert('RGB')
defsplit_image(img,part_size=(64,64)):
w,h=img.size
pw,ph=part_size
assertw%pw==h%ph==0
return[img.crop((i,j,i+pw,j+ph)).copy()\
foriinxrange(0,w,pw)\
forjinxrange(0,h,ph)]
defhist_similar(lh,rh):
assertlen(lh)==len(rh)
returnsum(1-(0ifl==relsefloat(abs(l-r))/max(l,r))forl,rinzip(lh,rh))/len(lh)
defcalc_similar(li,ri):
#returnhist_similar(li.histogram(),ri.histogram())
returnsum(hist_similar(l.histogram(),r.histogram())forl,rinzip(split_image(li),split_image(ri)))/16.0
defcalc_similar_by_path(lf,rf):
li,ri=make_regalur_image(Image.open(lf)),make_regalur_image(Image.open(rf))
returncalc_similar(li,ri)
defmake_doc_data(lf,rf):
li,ri=make_regalur_image(Image.open(lf)),make_regalur_image(Image.open(rf))
li.save(lf+'_regalur.png')
ri.save(rf+'_regalur.png')
fd=open('stat.csv','w')
fd.write('\n'.join(l+','+rforl,rinzip(map(str,li.histogram()),map(str,ri.histogram()))))
#print>>fd,'\n'
#fd.write(','.join(map(str,ri.histogram())))
fd.close()
importImageDraw

draw=ImageDraw.Draw(li)
foriinxrange(0,256,64):
draw.line((0,i,256,i),fill='#ff0000')
draw.line((i,0,i,256),fill='#ff0000')
li.save(lf+'_lines.png')
defgetIcon(filename):
large,small=win32gui.ExtractIconEx(filename,0)#
win32gui.DestroyIcon(small[0])
hdc=win32ui.CreateDCFromHandle(win32gui.GetDC(0))
hbmp=win32ui.CreateBitmap()
hbmp.CreateCompatibleBitmap(hdc,32,32)
hdc=hdc.CreateCompatibleDC()
hdc.SelectObject(hbmp)
hdc.DrawIcon((0,0),large[0])
hbmp.SaveBitmapFile(hdc,"save.bmp")
if__name__=='__main__':
#path=r'test/TEST%d/%d.JPG'
foriinrange(1,4):
getIcon(r'test/TEST1/%d.exe'%i)
print'RESULT:%d'%(calc_similar_by_path('save.bmp',r"test/TEST1/backup.bmp")*100)
#foriinxrange(1,7):
#print'test_case_%d:%.3f%%'%(i,\
#calc_similar_by_path('test/TEST%d/%d.JPG'%(i,1),'test/TEST%d/%d.JPG'%(i,2))*100)
#make_doc_data('test/TEST4/1.JPG','test/TEST4/2.JPG')
希望本文所述对大家的Python程序设计有所帮助。
