How to tell MATLAB to open and save specific files in the same directory -

-

I have to run an image processing algorithm on a number of images in a directory.

Code> name_typeX.tif , so there are different types of images for the given name.

Image processing algorithm takes an input image and output an image result.

I have to save this result as name_typeX_number.tif , where number is also an output from the algorithm given image

< P> Now ..

How do I tell MATLAB to open a specific typeX file? Also keep in mind that there are other non-TIF files in the same directory.

How to save the result as name_typeX_number.tif ?

The result can be saved in a single directory where input images are present. How do I tell MATLAB to treat the results that are saved as input images?

I have to run it as a background code on the server ... so no user input is allowed.

It seems that you want to get all the files in a directory, whose name is a certain format , Then process them automatically You can do this by using the function to get a list of file names in the existing directory, then using the function to find the file name, you can match a certain pattern. Here's an example: 

  fileData = dir (); % #% # Get the structure of data for the files in the existing directory fileName = {fileData.name}; Match the file names in a cell array index = regexp (filename, ...% # with a file name if it is '^ [A-Za-z] + _ Type \ d + \. Tif $') ; % # Was executed with at least one letter, # _type`, at least one number,% #, and #% with '.tif' inFiles = fileNames (~ SELFAN (@IsMPTY, index) ; % # Get the names of the matching% # files in a cell array

Once you create a cell array of files in the inFiles that you want the naming pattern you want , You can simply loop on the files and you can do your processing. For example, your code might look like this: 

  nFiles = numel (inFiles); Get the number of input files for% # IFile = 1: nFiles% # In the input files loop; File = files {iFile}; % # Get the input = file in the input file; Load% # image data [outImg, someNumber] = process_your_image (inImg); Execute image # file data = [strtok (inFile, '.') ... Remove the '.tif' from the% # input file, '_' ...% # attach an underscore, num2str (someNumber). Attach the% # number as a string, and '.tif']; Adding #% `.tif` to rewrite (outImg, outFile); % # Write a new image data at the end of a file

The example function above,

windows - Heroku throws SQLITE3 Read only exception -

After I deploy the app to Heroku, I have to run migration scripts and get this error message ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init ' how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads. I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's

lex - Building a lexical Analyzer in Java -

I am currently learning lexical analysis in compiler design. To know how a lexical analyzer actually works, I am trying to build myself. I am planning to make it in Java The input to the lexical analyzer is a .tex file that is of the following format. \ section {script} {intro} \ section {Scope} arbitrary text \ section {relevance} uncontrolled text \ subdivision (profit) arbitrary text \ subsubsection {in real life} \ subdivision {Ingredient} \ end {document} The output of the lecture may be a table of contents with a page number in another file. 1 Introduction 1 1.1 Scope 1 1.2 Relevance 2 1.2.1 Benefits 2 1.2.1.1 Real life 2 1.2.2 loss 3 I hope that This problem is within the scope of Language Analysis Read the .exe file and check '\' and continue to check whether it is actually on search In the sectioning command is set to indicate whether or not a flag variable is the type of sectioning. I hope the above approach will work for the construction of Lexa

python - rename keys in a dictionary -

-
I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly. For example, my keys are like this: '1', '101', '11' and I may need them: '001', '101', '011' What is doing, but I know that there is a better way tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction. for sorted (D, key = int): print '% s:% R'% (k, d [k]) < / Div>
