I don’t know how to solve the last pieces












0












$begingroup$


So, I almost finished a rubik’s cube, but the last 3 pieces are not in their places (green on red face, blue on green face, and red on blue face). Apart from these, the other faces are done.



The proof



How can I finish solving the cube?

    Although the duplicate I linked to is about switching two corner pieces, and you want to switch two edge pieces, the answer is the same. It is not possible with normal moves, and you will have to take the puzzle apart.

If the three edge pieces you want to rotate are on the top layer at front, left and right, then the move $F^2UM^{-1}U^2MUF^2$ will permute them cyclically where $F$ means rotating the front face $90^{circ}$ clockwise (so $F^2$ means rotating it $180^{circ}$), $U$ means rotating the top (upper) face $90^{circ}$ clockwise, and $M$ means rotating the vertical "middle slice" perpendicular to the front face $90^{circ}$ towards you. See here for an animation.



This will move front $rightarrow$ left $rightarrow$ right $rightarrow$ front which is actually the reverse of the direction you want; so either do it twice or do it backwards meaning $F^2U^{-1}M^{-1}U^2MU^{-1}F^2$. (Take the steps in reverse order, inverting each one, noting that e.g. $F^2$ is its own inverse.)

            How to label and detect the document text images

            Image
            1 $begingroup$ This is what I mean as document text image: I want to label the texts in image as separate blocks and my model should detect these labels as classes. NOTE: This is how the end result should be like: The labels like Block 1, Block 2, Block 3,.. should be Logo, Title, Date,.. Others, etc. Work done: First approach : I tried to implement this method via Object Detection, it didn't work. It didn't even detect any text. Second approach : Then I tried it using PixelLink. As this model is build for scene text detection, it detected each and every text in the image. But this method can detect multiple lines of text if the threshold values are increased. But I have no idea how do I add labels to the text blocks. PIXEL_CLS_WEIGHT_all_ones = 'PIXEL_CLS_WEIGHT_all_ones' PIXEL_C...
