 ##Objectives
 
-Practice sorting arrays by selection and the bubble method.
-Practice the use of decision and repetition structures.
-Use methods from the `vector` C++ class.
-Use the methods of the `QImage` class from `Qt` to manipulate an image’s pixels.
-Learn about the median filter for image processing.
+1) Practice sorting arrays by selection and the bubble method.

+3) Use methods from the `vector` C++ class.
+
+4) Use the methods of the `QImage` class from `Qt` to manipulate an image’s pixels.

 This laboratory experience is an adaptation of the nifty assignment presented by John Nicholson in [1].
 
 
 Before arriving at the laboratory you should have:
 
-Reviewed the selection sort and bubble sort algorithms.
-Familiarized yourself with the `push_back()`, `at(i)`,  `size()`, `clear()` methods in the C++ `vector` class.
-Familiariezed yourself with the `width()`, `height()`, `pixel(i, j)`, `setPixel(i,j, pixel)` methods in the `QImage` class from `Qt`.
-Studied the concepts and instructions for the laboratory session.
-Taken the Pre-Lab quiz that can be found on Moodle.

-**Figura 2.** Illustration of the median filter algorithm for a given pixel. The pixel’s colors are determined in the three images, then the median is calculated. The median of the pixel is used in the corresponding position of the merged image.

 ### Examples:
 
-`QRgb myRgb = qRgb(0xff, 0x00, 0xff);`: Assigns to `myRgb` the value `0xff00ff` that represents the color ![figure3.png](images/figure3.png)
+1) `QRgb myRgb = qRgb(0xff, 0x00, 0xff);`: Assigns to `myRgb` the value `0xff00ff` that represents the color ![figure3.png](images/figure3.png)
 
 Notice that the value of `0xff00ff` represents the values `0xff`, `0x00`, `0xff`, that correspond to the red, green and blue components of `myRgb`.

 then `originalImage.pixel(2,1)` returns the `rgb` value that represents the color blue (`0x0000ff`).
 
-3. The following instruction assigns the red color to the pixel in position `(2, 3)` in the edited image: 
+3) The following instruction assigns the red color to the pixel in position `(2, 3)` in the edited image: 
 
 `editedImage.setPixel(2,3,qRgb(0xff,0x00,0x00));`.
 
-4. The following instruction assigns a `greenContent` the value of the green value contained in the pixel `(1, 1)` of the `originalImage`:
+4) The following instruction assigns a `greenContent` the value of the green value contained in the pixel `(1, 1)` of the `originalImage`:
 
 `int greenContent = qGreen(originalImage.pixel(1,1));`.
 
-5. The following code assigns to the red component of the pixel `(1, 1)` of `editedImage` the average of the values of the red tone that are in pixel `(1, 1)` of `originalImage1` and `originalImage2` and does the same to the green and blue components.

 #### Instructions
 
-Complete the `Median` function that receives a vector of integers. The `Median` function should invoke the `Sort` function to order the integers and calculate the median. The function returns the calculated median.

 ####Ejemplo: 
 Supón que debemos hallar la mediana de los tres píxeles con valores `0xff223344`, `0xff112233`, `0xff001155`.
 
-* La mediana del componente rojo es 0x11 (dado que los componentes rojos son `0x22`, `0x11` y `0x00`.
-* La mediana del componente verde es 0x22 (dado que los componentes verdes son `0x33`, `0x22` y `0x11`.
-*  La mediana del componente azul es 0x44 (dado que los componentes azules son `0x44`, `0x33` y `0x55`.
+* La mediana del componente rojo es 0x11 (dado que los componentes rojos son `0x22`, `0x11` y `0x00`).
+* La mediana del componente verde es 0x22 (dado que los componentes verdes son `0x33`, `0x22` y `0x11`).
+*  La mediana del componente azul es 0x44 (dado que los componentes azules son `0x44`, `0x33` y `0x55`).
 
 Por lo tanto, la mediana de los píxeles sera `0xff112244`, compuesto por las medianas de los componentes de colores rojo, verde y azul.

-    Nota que el valor `0xff00ff` representa los valores `0xff`, `0x0`, `0xff`, que corresponden a los componentes rojo, verde y azul de `myRgb`.
