Decode image bytes data stream to JPEG

由 守給你的承諾、 提交于 2021-02-11 14:35:31
问题 I am struggling to successfully decode a JPEG image from bytes, back to JPEG again. I started from encoded frame from a MJPG bytes stream, which I want to decode in order to manipulate with OpenCV. I am a bit of a newbie at Python, numpy, opencv etc! I now have the frame JPG data in a text file as: b'\xf\xd8\xff\xdb\x00....etc etc for purposes of testing: code seems to fail when I try to Resize the numpy array to the original video stream resolution (640, 480) on line 14 (npFlat.reshape((640

Comprehensive character replacement module in python for non-unicode and non-ascii for HTML

由 人走茶凉 提交于 2019-12-08 04:06:57
问题 Is there a comprehensive character replacement module for python that finds all non-ascii or non-unicode characters in a string and replaces them with ascii or unicode equivilents? This comfort with the "ignore" argument during encoding or decoding is insane, but likewise so is a '?' in every place that a non translated character was. I'm looking for one module that finds irksome characters and conforms them to whatever standard is requested. I realize that the amount of extant alphabets and

Creating TfRecords from a list of strings and feeding a Graph in tensorflow after decoding

问题 The aim was to create a database of TfRecords. Given: I have 23 folders each contain 7500 image, and 23 text file, each with 7500 line describing features for the 7500 images in separate folders. I created the database through this code: import tensorflow as tf import numpy as np from PIL import Image def _Float_feature(value): return tf.train.Feature(float_list=tf.train.FloatList(value=[value])) def _bytes_feature(value): return tf.train.Feature(bytes_list=tf.train.BytesList(value=[value]))

I've never done this before and am not sure why it's outputting the infamous � encoding character. Any ideas on how to output characters as they should (ASCII+Unicode)? I think \u0041 - \u005A should print A-Z in UTF-8, which Firefox is reporting is the page encoding. var c = new Array("F","E","D","C","B","A",9,8,7,6,5,4,3,2,1,0); var n = 0; var d = ""; var o = ""; for (var i=16;i--;){ for (var j=16;j--;){ for (var k=16;k--;){ for (var l=16;l--;){ d = c[i].toString() + c[j].toString() + c[k].toString() + c[l].toString(); o += ( ++n + ": " + d + " = " + String.fromCharCode("\\u" + d) + "\n<br /
