    extra white region in Image convolution with first order guassian derivative

    Hi all, My image process work steps involves downsampling, despeckling and Image convolution with first order guassian derivative.While doing convolution i get extra white space region at the higher row index values..it may cause error in my work as the next step is intensity plot against...

    encoders truth table

    The truth table is for decimal to binary.Since the inputs and outputs are active low.You will get the binary code for X2, when it becomes '0' .(Since it is high prior to X1,the value of X1 can be 0 or 1 means don't care and since X1 is low prior to all other inputs ,they must be '1' .they must...

    matlab function load faces in digital image processing

    When we use the function load faces it says that it stores data from sub directories male and female with gender value.. Means if we have 50 images it will save data in (face,1),(face,2) etc.which shows matrix having values less than one..Now how do we get the actual image values of this (face,1) ?

    encoders truth table

    I will discuss the design of binary encoder .we must consider three outputs Y0,Y1 and Y2 for the inputs X0 to X7. From the truth table it can be noticed that Y2 becomes '1 or high' either X0 or X1 or X2 or X3 becomes high,implies the expression becomes Y2= X4 + X5 +X6+X7. Proceeding the same...

    encoders truth table

    The truth table from first link is the correct decimal to binary encoder.You can easily note that the Y output gives the binary code of the input signal which is active (here high)...Eg: For the input X0 or decimal zero you get binary output as 000..Similarly for all other input... Second link...
