00:41:57 Jennifer Woodward-Greene: working on it 00:42:02 Ren Ortega: No, I'm trying to open it 00:42:57 Jennifer Woodward-Greene: got it... where is green yes? 00:43:26 Suzy Stillman: In the participants pane 00:43:45 Kerrie Geil: https://kerriegeil.github.io/NMSU-USDA-ARS-AI-Workshops/learn/ 00:44:32 Kerrie Geil: green yes, should be in the participant panel 00:53:51 Timothy: Can we create breakrooms so we can go ahead and be assigned for specific assistance in case we need them? 00:54:01 Andrew Russ: im in 00:54:58 Jian.Chen: Do not know what to do 01:07:36 Jennifer Woodward-Greene: if you do not explicitly call np.asarray, what is the format with imageio? 01:17:13 Timothy: Please can I be assigned to a breakout room. I am having some trouble here. Thanks 01:40:18 Andrew.Russ: Bright diagonal element bottom left to top right 01:40:20 Jennifer Woodward-Greene: There is a diagonal whitish (lighter) line going from the lower left corner to the upper right corner in this sample of the image. 01:40:26 ARS - Kossi Nouwakpo: A bright line going across the image? 01:40:27 Amy Hudson (she/her): a lighter slash going across 01:46:45 ARS - Kossi Nouwakpo: channels swapped? 01:46:50 Andrew.French: doesn't like leaving cmap as empty field 01:46:51 Jennifer Woodward-Greene: It is imposing additional channels 01:47:05 Jennifer Woodward-Greene: and they are mixing 01:47:37 Lucas Heintzman: Would you please scroll up to view the code again? 01:49:47 Lucas Heintzman: All good now. 01:54:08 Jennifer Woodward-Greene: I think you can, in that case convert in Matplotlib 01:55:12 Laura Boucheron: Yes--you can convert between grayscale and color. We'll talk about that in more detail in Section 3. 02:31:22 Ren Ortega: Yellow in bottom right 02:32:59 Jennifer Woodward-Greene: Similar contributions of red and green on lower right half, similar contributions of red and blue on upper left half, with half as much from green 02:33:10 Maria Laura Cangiano: yellow in bottom right and getting darker/purple to the upper left 02:34:31 Jennifer Woodward-Greene: Same to see differences, harder to know what they mean! 02:38:48 Jennifer Woodward-Greene: Shows the upper left corner has the purple backdrop, the lower right is on the top of the large green pepper in the rear left of the image. 02:42:35 ARS - Kossi Nouwakpo: Why did the "cmap" argument not make a difference? 02:46:20 zhanyou xu: plt.figure(figsize=(20,20)) plt.imshow(I_pepper) plt.axis('off') plt.title('Cameraman, grayscale') plt.plot([100,100],[100,110],[0],'y-',linewidth=3) plt.plot([110,110],[100,110],[1],'y-',linewidth=3) plt.plot([100,110],[100,100],[2],'y-',linewidth=3) plt.plot([100,110],[110,110],'y-',linewidth=3) plt.show() 02:48:47 Jennifer Woodward-Greene: possibly the channels of the 'yellow' line.... 02:49:33 Jennifer Woodward-Greene: the last line (bottom) is yellow... 02:52:17 Jennifer Woodward-Greene: Yes good... 1:30 in the East! :) 02:53:29 Lucas Heintzman: You mean lessons for Wednesday? 02:53:48 Kerrie Geil: yep apologies. I mean for Wednesday, day 2 02:54:58 Kerrie Geil: same, I'm going to run out, but will be back in 30 minutes or so 04:03:47 Andrew.French: whos is a system command so has to have percent? 04:04:51 Andrew.French: yes thx 04:11:15 Andrew.French: output data is float64? 04:11:55 Andrew.French: ok , size of image now huge 04:12:39 Andrew.French: 1.5 Mb 04:15:09 Maria Laura Cangiano: 384 x 512 04:15:10 Jennifer Woodward-Greene: (256, 256, 3) 04:15:11 Timothy: 384x512 04:15:11 Amy Hudson (she/her): 384x512 04:15:20 Jerry M: I_pepper_gray.shape 04:15:24 ARS - Kossi Nouwakpo: 384x512x3 04:16:08 ARS - Kossi Nouwakpo: 384x512 04:16:11 Jennifer Woodward-Greene: object.size = bytes too 04:16:56 Maria Laura Cangiano: 1 04:16:58 ARS - Kossi Nouwakpo: 1 04:17:00 Gerardo A Armendariz: 1 04:17:19 Timothy: yes 04:17:20 ARS - Kossi Nouwakpo: yes 04:17:22 Amy Hudson (she/her): yep 04:19:16 Jennifer Woodward-Greene: decimal places in floats 04:19:18 Amy Hudson (she/her): precision 04:20:21 Maria Laura Cangiano: 0.029 and 1 04:26:46 Timothy: Could you take this conversion from 0-255 to 0-1 a form of image filtering? 04:34:39 ARS - Kossi Nouwakpo: zeros and ones 04:34:57 ARS - Kossi Nouwakpo: it got thresholded 04:37:12 Andrew.French: can you change weigths on scikit function 04:38:10 Andrew.French: how about logarithmic 04:38:40 Andrew.French: sure 04:43:45 Andrew.French: thx 04:53:41 Maria Laura Cangiano: 256X256X3 04:53:47 Matthew.McEntire: 256x256x3 04:54:17 Matthew.McEntire: yes 04:54:18 Timothy: yes 04:54:37 Maria Laura Cangiano: uint8 04:55:14 Jerry M: type(I_camera_rgb[0][0][0]) 04:56:08 Jerry M: this is habit.. I always check the first element 04:58:06 Maria Laura Cangiano: 7 and 253 04:58:06 Matthew.McEntire: 7 , 253 04:58:10 Timothy: 7:253 04:58:29 Matthew.McEntire: yes 05:01:37 Jennifer Woodward-Greene: try to note the number in the brackets on the left!! 05:02:40 Maria Laura Cangiano: just like the original 05:02:43 Jennifer Woodward-Greene: no color 05:02:46 Matthew.McEntire: gray scale 05:02:47 Timothy: it looks like a gray scale 05:02:47 Gerardo A Armendariz: same 05:04:32 Kerrie Geil: To anyone trying to run on a reserved node on the HPC today. I pasted the instructions wrong earlier! The reservation is actually under my name for everyone. So on JupyterHub spawner page in the SLurm batch optional args field you will type: --reservation=kerrie.geil_85 05:08:14 Kerrie Geil: This will still only work for the few people I mentioned earlier: Amy, Gerardo, Zhanyou, Max, Elizabeth Chin, Andy French. If you aren't on the list and want to run this workshop on the HPC reserved node, let me know and I'll have you added 05:10:56 Maximilian Feldman: Thanks! 05:15:47 Amy Hudson (she/her): how do we comment in python again? 05:23:21 Suzy Stillman: # before the commented line 05:24:26 Amy Hudson (she/her): thx! 05:24:38 Jennifer Woodward-Greene: pixelated 05:24:44 Amy Hudson (she/her): squished 05:26:37 Lucas Heintzman: Would another option be to just as NullValue cells to the exterior of the image to compensate for size issues? 05:26:59 Andrew.French: is there an easy to find hyperlink to the skit functions and their options 05:28:16 Kerrie Geil: https://scikit-learn.org/stable/user_guide.html 05:28:43 Kerrie Geil: whoops 05:29:07 Andrew.French: hard for me to remember the syntax and options for each 05:29:58 Laura Boucheron: https://scikit-image.org/docs/stable/ 05:38:26 Andrew.French: for some reason skimage now showing undefined in my window 05:39:01 Andrew.French: my own 05:39:26 Andrew.French: get error message function not avail 05:39:55 Laura Boucheron: import skimage.color import skimage.transform 05:40:22 Jennifer Woodward-Greene: typo?
