The previous blog mentions a one-way association: nhibernate-one-to-many mappings-unidirectional correlation. This article is about two-way correlation.The difference between two-way association and one-Way association is: Both sides can maintain the relationship, such as I query on either side, the other side of the information can also be queried, and other modifications deleted as long as the settings, also can. This is reflected in the code: becau

First, what is the associationAssociation (correlation): During script playback, the client makes a request to make the correct request to the server by locating the left and right boundary values defined by the associated function (that is, association rules), finding the corresponding value in the contents of the server's response, and replacing the static value at the time of the recording with the variable. This method of dynamically acquiring ser

-level index query to a record,We're going to have to go again. The primary key index goes to the table to find the other columns that are needed, naturally slow. is there any way to optimize this limit paging query? To download the deferred correlation technique, you can optimize the SQL, and the following statements are optimized:SELECTshotel_id as Hotelid,mroom_type_id as Mroomtypeid,available_date as Availabledate,Result_status as Resultstatus,Ope

Three ways to do MySQL related queries:SELECT * from film JOIN film_actor on (film.film_id = film_actor.film_id);SELECT * from film JOIN film_actor USING (film_id); --You can use the using () when the two field names are the same for the associated tableSELECT * from film, film_actor WHERE film.film_id = film_actor.film_id;Refine the associated query: Make sure that there is an index on the column in the on or using clause.

. From the above calculation formula can be seen, its main calculation is the local mean and average distribution mean variance, the mean of the calculation of many optimization methods, typical such as cumulative integration chart. And on the average distribution of the optimization of mean variance, we recommend you see here: Http://fiji.sc/Integral_Image_Filters, the core of the demolition formula is:after this derivation, it can be seen that the local mean variance can also be achieved quick

The following is an introduction to hibernate, another way of associating mappings.There are two implementation strategies for one-to-single affinity mappings: primary key affinity mappings and unique foreign Key association mappings.PRIMARY KEY affinity mapping: Let two objects have the same primary key value to justify the one by one correspondence between them; The database table does not have additional fields to maintain the relationship between them, and is only associated with the primary

out of bounds, typically add 0 or add values of the original boundary pixelsIt can be seen that the main difference is that when calculating convolution, convolution cores are rotated first.There is no need to rotate the relevant cores in the calculation process.Discrete unit shock: We will contain a single 1 and the rest is all 0 of the functions become discrete unit shocks.Important properties: A function is associated with a discrete unit shock, which produces a function in the impact positi

: 4. the normalized cross correlation (NCC) formula is as follows: 5. The sum of hamming distances (SHD) formula is as follows: The BIT () in formula 5 indicates the number of 1 contained after the pixel is converted to binary. The entire formula indicates that the two local images are first different or a bit, then count the number of the first after all pixels are converted to binary. Just take the minimum one. I used only MATLAB to implement the f
