You shouldn't be using JCh_to_Jab with CAM16. The CAM16-UCS J'a'b' is a very bizarre construct compared to CIELAB, as a' and b', when converted to cartesian, output hue and ln(1 + 0.0228M)/0.0228, where M is colorfulness. It does not output hue and chroma. Likewise, J' is equal to 1.7*J/(1 + 0.007J). Thus it is almost J, but not.
You should probably just convert straight from XYZ to JCh, without using the UCS.
Thanks for correcting. About color science, something I don't know keeps coming up.
Is that why CAM16 JMh exists?
Anyway, Jab_to_JCh is just used to convert cartesian to cylindrical. Not to get actual J, C, h value.
Relative position on the CAM16-UCS's a-b plane is what I want to get. So, I think it's fine for the purpose.
(I don't want to use CIELAB because its hue prediction is bad, especially reddish blue.)
The biggest gripe I have with Lego's creation of the 18+ tag is that the age suggestion now has more to do with who lego thinks will enjoy a set, rather than who is capable of building the set. Fans know what they can build, so the age suggestion in my mind was for parents who knew what properties their children enjoyed, but didnt know what their kids were capable of building. I still think that is the case for the other age ranges, but for 18+, I guess lego now thinks adults need to be told what is ok for them to buy. This is most apparent with the BTS set (https://www.lego.com/en-us/search?q=Bts), an 18+ set with simple building techniques targeting a brand mostly enjoyed by teenagers. Compare this to the Airbus heli (https://www.lego.com/en-us/product/airbus-h175-rescue-helico...) which is more aptly labelled at 11+ while having twice as many pieces and being a technic build.
That being said, I actually revise my thesis. Looking back, Lego used to have age ranges listed: https://images.brickset.com/sets/large/7893-1.jpg , however, it appears all sets now just list a single age with a plus sign. Thus it seems Lego has actually shifted more towards the age simply being capability, with the 18+ designation being the outlier.
I would argue everyone should learn c purely from a linux/free software point of view. So many open source libraries are written in c, and getting as many eyes as possible on that source code would definitely be beneficial.
Like video, webp uses limited ycbcr, as opposed to jpeg which uses full ycbcr. This leads to grayscale jpeg looking perfect on monitors that use full rgb values, as opposed to webp which will have slight banding issues when displaying grayscale content.
Webp is encoded using limited ycbcr values as opposed to jpeg which uses full range ycbcr values. When converting jpeg to webp, there will be banding. Grayscale limited ycbcr when converted to full rgb during display ill also have banding.
Webp really doesnt have a banding issue unless you convert jpeg or display purely grayscale content.
While price per piece may have remained relatively constant, Lego has been pushing out more and more expensive sets. I remember when the most expensive set was the 400 dollar death star, and that was the only 400 dollar set. Now, there are 26 sets that are 400 dollars or more, with 7 of those sets being 600 dollars or more, and the most expensive set being 850 dollars. All of this to target more adult fans of lego.
"Releasing Palestinian prisoners, allowing cash transfers, as the Qatari envoy comes and goes to Gaza as he pleases, agreeing to the import of a broad array of goods, construction materials in particular, with the knowledge that much of the material will be designated for terrorism and not for building civilian infrastructure, increasing the number of work permits in Israel for Palestinian workers from Gaza, and more. All these developments created symbiosis between the flowering of fundamentalist terrorism and preservation of Netanyahu’s rule."
The idea that these points prove that Netanyahu purposefully bolstered Hamas is tenuous at best.
"The percentage of all births to unmarried women was 40.0% in 2021, down 1% from 2020 (40.5%) (Table 9) (15). The
percentage of all births to unmarried women peaked in 2009 at
41.0% (13,15).
The percentage of nonmarital births in 2021 increased from
2020 for non-Hispanic Asian (12.6% in 2021) and Hispanic
(53.2%) women. The percentage decreased for non-Hispanic
White (27.5%), non-Hispanic Black (70.1%), and non-Hispanic
AIAN (68.5%) women. The percentage was unchanged for non-
Hispanic NHOPI women (51.8%). The number of nonmarital
births was essentially unchanged from 2020 (1,464,121) to
2021 (1,464,455) (15).
Nonmarital birth rates declined from 2020 to 2021 for
women in age groups under 30, with the rate for teenagers
aged 15–19 dropping 7% (to 13.0 per 1,000 in 2021), and the
rate for females aged 15–17 declining to another all-time low
(5.6). Conversely, the nonmarital birth rate reached a historic
peak of 38.2 for women aged 35–39. The rates were essentially
unchanged for women aged 30–34 (58.5) and 40–44 (11.4)."
So it appears to be trending down from a high in 2009.
This isn't necessarily true. I tried to measure the PWM of my Cree and Philips smart bulbs, and what I found is that for RGB mode, they used PWM, but for white mode (which appears to use a 2700k led and 6500k led) they current dim both leds, and then use PWM to pulse the warm and cool leds on and off to achieve the target warmth. The Philips bulb actually syncs this so while the warm led is on, the cool led is off, and vice versa, so even though there is flicker, the total lumens eminating from the bulb is constant.
