识别流程:
流程说明:
1.Gif转png,每一帧保存为png格式图片 2.每张png图片进行单独识别 3.统计每个对应位置字符频率,每个位置取最高频率字符作为对应位置字符识别结果 4.拼接指定长度字符作为最终识别结果
抽帧模块:
def gif_to_png(length,image):
'''
gif抽帧
:param length:
:param image:
:return:
'''
try:
yzm_list = []
for i in range(1, length):
image.seek(i)
stream = BytesIO()
image.save(stream, 'PNG')
s = stream.getvalue()
yzm_list.append(s)
return yzm_list
except Exception as e:
print(e)
return None
