deep learning image segmentation tutorial

Depth learning training needs to mark the location and category of images, used before is called Bbox-label-tool-master, the encounter of large images is not complete, there is no adaptive scaling, this is the improved Python script. Directory structure: Picture directory name images, label directory name labels, image directory under various categories of directory name to 001,002,003,... The format name.

Note that the Inception_v3 training picture is of type (299,299,3), classified as 1001, so we need to convert the dataset to this format before making predictions, see read_files.py file; then we load inception_ V3 network and its given weights to predict, see test.py file, the training results are shown in the image below: read_files.py #coding =utf-8 import tensorflow as TF import numpy as NP import OS from PIL import

images because it lowers the speed of the program 4--in order to fix this problem, OPENCV uses the---Reference counting mechanism, the idea is to let each mat object have its own message header, but share a matrix. Implemented by having the matrix pointer point to the same address. The copy constructor copies only: the 1--information header 2--The matrix pointer and not the matrix. /********************************************************************************************* Program

understand computer knowledge, psychology and philosophy. Artificial intelligence consists of a very wide range of sciences, consisting of a variety of fields, such as machine learning, computer vision, and so on, in general, one of the main goals of AI research is to make machines capable of doing complex work that normally requires human intelligence. But different times, different people's understanding of this "complex work" is different. In Dece

The goal of this blog is to introduce the introduction of torch Bloggers use the Itorch interface to write, the following images to show the code.If you can't remember the name of the method can be in the Itorch Point "tab" key will have intelligent input, similar to MATLAB Simple Introduction to String,numbers,tables The action of the string is a single quotation mark, and then the print () function in the second row is a bit like the cout in C + +, which can be displayed accord

Use of functionsThis is the definition of the function, the declaration of the keyword + defined function name + the name of the formal parameter, the blogger returns two values, the function of the specific functions in the back againThis is the initialization of a 5x2 matrix, and the initial value is 1. Here's a way to initialize the matrix.This is to declare a 2x5 matrix before calling the fill () method whose values are all initialized to 4.Input a A A, a matrix into the addtensors function,

function and a macro Macro inline functions Processing mode Processed by the preprocessor, just for simple text substitution Handled by the compiler, the body of the function is embedded in the calling place. But inline requests can also be rejected by the compiler Type check Do not do type checking Features that have normal functions are checked for parameters and return types. Side effects Yes

please refer to http://www.deeplearning.net/tutorial/dA.html Self-coding for the original EnglishA self-coding accepts x as input and maps to a hidden layer to represent Y:where S is a nonlinear function, such as SIGMOD. Y is mapped to Z with the same shape as x through a decoder, through a similar transformation:Z can be seen as a prediction of x, given code y. Optionally, W ' can be the transpose of W, W ' =WT, the goal is to optimize the para
