Interpolating along the 2-D image slices

佐手、 提交于 2019-12-01 17:17:56
I have a set of 100 2-D image slices of the same size. I have used MATLAB to stack them to create a volumetric data. While the size of the 2-D slices is 480x488 pixels, the direction in which the images are stacked is not wide enough to visualize the volume in different orientation when projected. I need to interpolate along the slices to increase the size for visualization. Can somebody please give me an idea or tip about how to do it? Edit: Anotated projected microscopy-images The figure 1 is the top-view of the projected volume. The figure 2 is the side-view of the projected volume. When I

2d array of lists in python

廉价感情. 提交于 2019-12-01 16:32:22
问题 I am trying to create a 2d matrix so that each cell contains a list of strings. Matrix dimensions are known before the creation and I need to have access to any element from the beginning (not populating a matrix dynamically). => I think some kind of preallocation of space is needed. For example, I would like to have a 2X2 matrix: [['A','B'] ['C']; ['d'] ['e','f','f']] with support of traditional matrix access operations, like (Matrix[2][2]).extend('d') or tmp = Matrix[2][2] tmp.extend('d')

Convert 3D Raycast to Raycast2D

不羁岁月 提交于 2019-12-01 14:25:30
I have this code below which could control a touched player among 3 players. I was able to implement it by like sort of "cheating" by way of adding a 3D cube behind a 2D sprite since my game should be in 2D and I am having hard time implementing it in 2D. I'm really confused on how to do it in 2D because I'm really confuse on the parameters. Although I already implemented it by the way mentioned above, I still want to implement it in pure 2D. And because I have this problem when the selected player moves, the sprite moves faster. public GameObject target = null; // Use this for initialization

How to get the size of dynamically allocated 2d array

£可爱£侵袭症+ 提交于 2019-12-01 13:32:21
问题 I have dynamically allocated 2D array. Here is the code int **arrofptr ; arrofptr = (int **)malloc(sizeof(int *) * 2); arrofptr[0] = (int *)malloc(sizeof(int)*6144); arrofptr[1] = (int *)malloc(sizeof(int)*4800); Now i have to know that how many bytes are allocated in arrofptr,arrofptr[0],arrofptr[1]? is there any way to know the size? if we will print sizeof(arrofptr); sizeof(arrofptr[0]); sizeof(arrofptr[1]); then it will print 4. 回答1: You can't find size of arrofptr , because it is only a

Store 2D array (String) to file and retrieve it

夙愿已清 提交于 2019-12-01 12:28:17
I have made a simple program that has a 2D String array storing lots of data. I have searched a lot of places for how to store and retrieve 2D arrays. I want to save the data in my array at the end of the program and have this data retrieved upon the start of the program. I have tried: ObjectOutputStream toFile = new ObjectOutputStream(new FileWriter("array.DATA")); toFile.writeObject(array); This came up with the error: incompatible types: FileWriter cannot be converted to OutputStream I only know basic programming so try to be easy on me and explain everything you say thoroughly. If I'm

Rendering multiple 2D images in OpenGL-ES 2.0

走远了吗. 提交于 2019-12-01 11:18:49
I am new to OpenGL, and trying to learn ES 2.0. To start with, I am working on a card game, where I need to render multiple card images. I followed this http://www.learnopengles.com/android-lesson-four-introducing-basic-texturing/ I have created a few classes to handle the data and actions. MySprite holds the texture information, including the location and scale factors. Batcher draws all the sprites in one go. It is rough implementation. ShaderHelper manages creation of shaders and linking them to a program. GLRenderer is where the rendering is handled (it implements `Renderer`.) Q1 My

Getter returning 2d array in C++

旧巷老猫 提交于 2019-12-01 11:07:51
this is my first post on SO, even though i've spent some time already here. I've got here a problem with a function returning a 2d array. I have defined a private 2d int array property int board[6][7] in my Game class, but i don't know how to create a public getter for this property. These are relevant parts of my game.h: #ifndef GAME_H #define GAME_H class Game { public: static int const m_rows = 6; static int const m_cols = 7; Game(); int **getBoard(); private: int m_board[m_rows][m_cols]; }; #endif // GAME_H Now what I would like is something like this in game.cpp (cause I thought array
